Easy question: Limit message size from any channel

Greetings Jay and SUNWmsgsr gurus,
Seems like a long time since I've posted in this forum. That's because things are working great! Anyway, I have a need to limit the message size for both outbound and incoming to 20MB. I added sourceblocklimit 20000 and blocklimit 20000 to my tcp_local line in imta.cnf.
This didn't seem to do the trick. Do you folks have another suggestion? Thanks for your help.
Sam K.

you've blocked messages over 20 megs in one channel. You have others.
tcp_intranet at least. If you have other channels you've created, you will need to add there, too.

Config mail accounts in difference OUs have difference limit message size

Mail Server is installed by Netscape Messaging Server 4.15.In Directory Server have alot of Organizational unit.I want to config mail accounts in difference OUs have difference limit sended and recieved message size.
Ex: OU 1 ( acc1,acc2...) : I want these accounts only sended and recieved mail limit message size is 1MB
OU 2 ( acc1,acc2.....):I want these accounts only sended and recieved mail limit message size is 2MB
Pls help me,Thanks
Trang nguyen

It's not truly obvious how to do it, but by configuring different channels for each OU (using rewrite rules), you can configure maximum sizes for sending/receiving messages. If it's quotas you're asking for, 5.2 doesn't do "domain-based" quotas for enforcement, but 6.0 does.

Limit message size per recipient domain

Is there a feature to set maximum message size per recipient domain (incoming emails) in the roadmap maybe?

While you cannot do it by 'domains' for maximum message size limitations, you can limit the connection mail hosts.
IE: domain1.com may use the connecting mail host of mail.domain1.com
domain2.com may use the connection mail host of mx.domain2.com
Then you can create new sendergroups for the respective domains mail servers to match, and with the sendergroup you will need to create a new mail flow policy with the size limits you would like to impose.
Once this is done, simply add the mail.domain1.com into the respective sendergroup and it will impose this limitation.
Key points to note:
Size limits should account for MIME inflation.
IE: 10mb limitation you want to implement should be 14MB on the mail flow policy to account for MIME inflation.
Alternatively, if you would like to do it 'by domain'
SImply increase your mail flow policy for the sendergroup that these domains normally match (under default it would normally be UNKNOWNLIST) and have it at 14MB (to allow for 10MB emails)
Then run a message filter (so it gets actioned at the start)
FilterDomain1:
if (mail-from =="@domain1.com") AND (body-size > 5M)
drop();
Etc. to impose the limits this way.
Note:
Body size refers to the size of the message, including both headers and attachments. The body-size rule selects those messages where the body size compares as directed to a given number.

Question about image size from app developer

Hi
I am developing an android app that prints through eprint, so this is directed to HP Staff
What is the correct size of a jpg image to take up the whole page?
In this app, i am unable to use PDF's, so i want to try using a full page jpg and insert the data onto that, then send the whole page to an eprint email address.
I tried a standard 612 X 792 pixel page (72 dpi), but it only takes up alittle more than a quarter page.
i need it to be the right size for any of the eprint printers.
thanks
--Karl

1: Decrease the size as you describe.
2. Go to File>New or Ctrl N
3. Make the box 8.5x11. Make sure the other data conforms to your image.
4. Now,holding down Ctrl-Shift, Drag the image to the new box and release the mouse. Your image will be centered in the box.
Note: there may be a method to do this including any adjustment layers, but I usually only do this as a last step, flattening a copy of the working file.

Optimization problems in downloading data of greater size from any URL.

Hi everyone !
I'm trying to download some resource from the internet by providing valid URL. My code takes almost 50-55 minutes to download. The same resource is downloaded within 3-5 minutes by using Internet Explorer and 3-4 minutes using Fire Fox at the same network and Kbps. The sample code is as under:
//I'm using apache's HTTP APIs
public static String url = "http://www.sk.ee/crls/esteid/esteid.crl"; //file size is approx: 10 MB
//httpMethod is instance of HttpMethodBase and I have initialized it with GET method
obj_httpMethod = new GetMethod( obj_httpUrl.getEscapedURI()
InputStream obj_is = obj_httpMethod.getResponseBodyAsStream();
ByteArrayOutputStream obj_data = new ByteArrayOutputStream();
//above code is working fine and giving proper input stream got from response.
//problem start from here....although this code is working ok but it is not optimized
//Is there any way to optimize the code
MyHttpTransporter.copyStream(obj_is, obj_data, 524288); //Buffer Size: 512K [512*1024]
//This method is working fine with files of small sizes but it is not doing well with greater file sizes e.g. 10MB
public static void copyStream(InputStream a_objIs, OutputStream a_objOs,
                                int a_iblockSize) throws Exception{
    System.out.println( "Buffer Size..: " + a_iblockSize);
    byte [] byte_Buffer = new byte[a_iblockSize];
    int i_byteRead = -1;
    while ( (i_byteRead = a_objIs.read(byte_Buffer, 0, a_iblockSize)) > -1) {
      System.out.println( "reading stream...." );
      a_objOs.write(byte_Buffer, 0, i_byteRead);
      System.out.println( "writing stream...." );
      System.out.println( i_byteRead );
System.out.println( i_byteRead );
The one thing found in the above code is that, it is ignoring my provided buffer size and always fetching max 2047 bytes from the resource.
Please help me in this regard as I'm unable to progress further in it.

Thanx for the help.
It makes some difference.
the sample code is:
//iblockSize = 524288 [512K]
//1
BufferedInputStream bis = new BufferedInputStream(a_objIs, a_iblockSize);
BufferedOutputStream bos = new BufferedOutputStream(a_objOs, a_iblockSize);
//2
BufferedInputStream bis = (BufferedInputStream)a_objIs;
BufferedOutputStream bos = (BufferedOutputStream)a_objOs;
//what do you suggest 1 or 2 ? BTW I'm using 1
If (2) works then behind the scenes the Apache code is already using Buffered streams (otherwise you would get a class cast exception) so there is going to be little advantage to using further buffering. Also, casting to buffered streams does not offer any performance advantage since any reading/writing you do will already be using the methods on the Buffered streams.
Do I need to concentrate on the block size [reduce or increase what is good practice]. Because again it is fetching maximum 5387B and on average it is fetching the 2047B. But it is improved a little bit.Though the buffer size of the Buffered streams can be set when constructed they cannot be changed later so if the Apache code is not setting the buffer size when it constructs the buffer then you are stuffed. Check the Apache documentation to see if you can change the buffering.
P.S. Of course, since it is open source, you can always modify the Apache code to increase the buffer size.
P.P.S. I always use HttpURLConnection for this and it seems pretty quick though I have never downloaded anything beyond a few hundred KBytes.

Easy Question:Select many rows from a table and execute BAPI for these rows

Hi Experts,
I have created one WD project. The WD project fetches some records of backend using BAPI and displays in a table. I have to select some rows from the table and then execute BAPI for selected rows.
How I can select multiple records from the table and then execute another BAPI for selected rows.
Regards,
Gary

Hi,
In the Node which you binded to the table create one more attribute of type boolean.
For example your node is as below:
//Table Node
TableNode
> Att1
> Att2
> isSelected(boolean) - Newly created attribute for this requirement.
//Result Node contains the elements selected in TableNode
ResultNode
>Att1
>Att2
Now in the table create one more Column with Checkbox as tablecell editor. Now bind this boolean attribute to that check box.
Now in the code you can get the selected rows by user as below:
for(int i=0;i<TableNode().size();i++)
if(wdContext.nodeTableNode().getTableNodeElementAt(i).getIsSelected()==true)
    IPrivateTestView.IResultNode element=wdContext.createResultNodeElement();
    element.setAtt1(wdContext.nodeTableNode().getTableNodeElementAt(i).getAtt1());
    element.setAtt2(wdContext.nodeTableNode().getTableNodeElementAt(i).getAtt2());
   wdContext.nodeResultNode().addElement(element);

I cannot access the Verizon Messages app from any computer. The message app works fine across my phone and tablets but I cannot use it on my desktop.

I get the following error message whenever I try to access the Web App for messages:
This mobile number does not have permission to send messages and cannot sign up for this service. Please contact the account owner for this mobile number to change permissions.
I tried Online Chat support but they could not solve the problem and suggested I post in the forum. All I am trying to do is access my text messages on my Desktop. I pay extra each month for Messages+. Works fine on my phone tablets, but not on my desktop or laptop.

gspam1, I know the importance of being able to take advantage of the Verizon Messages application on your computer. Let's look into this, together. What operating system do you have on your PC? Are you downloading the application for use with the phone number attached to your Smartphone? What type of phone do you have with us? Please share more details so we can resolve this for you.

Message size limit

Hi all,
I have a question regarding the message size for the mapping:
What is the size limit for messages when using the XSLT mapping methods?
What are the maximum message sizes (if any) for the other methods like ABAP mapping, Graphical mapping, JAVA Mapping and XSLT Mapping (JAVA) ?
Looking foward to hear from you:)
Regards
Markus

Hi Markus,
Just go through the belwo thread which talks about the same.
Wat is the maximu size of data XI can handle
Also go through the mapping performance which helps u in understanding the performance as well.

Message Size tracked from a send shape in TPE is set to -1

Hi
I am tracking the message size from a send shape in my orchestration using Tracking Profile Editor but the value that is stored in the BAM PI <Activity> table for message size is -1.
What might be the issue?

As you can see in the documentation below, when asking for the size of a message, the answer might or might no be there:
https://msdn.microsoft.com/en-us/library/microsoft.biztalk.message.interop.ibasemessage.getsize.aspx?f=255&MSPPError=-2147217396
When fImplemented returns false, it means that the size of the message cannot be determined at this time (I believe it is under these circumstances that BAM will return -1).
The underlying reason for this is because we are dealing with Streams, which at times might be "none-seekable", which means that "right now I cannot tell you the size, unless you load everything".

Difference message size of each virtual domain

Sun ONE Messaging Server 6.0 Patch 1 (built Jan 28 2004)
We has 5 virtual domains on my messaging server.
My customer want to limit message size each virtual domain on new channel.
domain1.com can deliver message size 5 MB to internet on channel tcp_domain1
domain2.com can deliver message size 6 MB to internet on channel tcp_domain1
domain3.com can deliver message size 10 MB to internet on channel tcp_domain1
Could you suggest me how to configure mapping and imta files.
Thanks you.

I think you're getting me confused, and you are also confused.
Please, let's start over, by defining exactly what it is you want to do.
Say, "I want to limit the size of mails sent FROM certain domains. I want to limit the size of mails DELIVERED do certain domains" if that is what you actually want to achieve.
If this is not what you want, please let me know exactly what it is that you're trying to achieve.
It is usually much better to tell us what your goal is, rather than how you thing you should get there.

How to log message size ?

Hi,
How can message size be logged in ALSB ? I mean "logged" in a general way, not specifically through a Log Action:
-using a Report Action ?
-using the JMX monitoring API ? In that case, is it possible to add a new statistic "Message Size" to the ressource type SERVICE ?
Thanks in advance.

Message size is not typically provided by service bus and this is an expensive operation. I believe there is an xquery function to determine the size of a variable. You can then save this value either using a pipeline alert, a logging action or a javacallout where you can write your own logging logic. If you use java callout you can also determine the message size from there.

Group message size limit bug

Recently some friends set up a group chat with 13 members. The chat works fine for everyone except me. My phone seems to not want any group chats with more than 10 people and it just splits the chat and makes new chats always excluding a few people. This really makes no sense considering the group chat works fine for all the other iphone users in the chat.

Hi,
i need to set a message size limit that applies to
both incoming and outgoing mail. I see there is an
user-attribute I can set on LDAP, mailmsgmaxblocks,
but the reference guide says that it is: "The size in
units of MTA blocks of the largest message that can
be sent to this user". I want the limit to apply to
messages SENT by an user, too.
I don't think that this can be an user-based
attribute, because mail it would not apply to users
not belonging to local domains sending inbound mail,
but there is an MTA-wide option I can set to do
this?I did find this option in the 2005Q4 messaging server reference guide:
<snip>
LDAP_SOURCEBLOCKLIMIT: The LDAP attribute to specify the maximum number of
blocks allowed in a user�s message. The MTA rejects messages containing more blocks than this from a user. An MTA block is normally 1024 bytes, but this can be changed
with the BLOCK_SIZE option in the MTA option file. This is a user analog to the sourceblocklimit keyword and has no default.
</snip>
This seems to describe exactly what you are after, I haven't personally tried it before.
Implementing will require jumping through a few hoops:
1. Extend your directory schema to add a new user attribute (you will need to dig through directory server manuals for help on this).
2. Add LDAP_SOURCEBLOCKLIMT=<attribute from (1)>
3. Add <attribute from (1)> to the users entry set to the the number of blocks of the maximum email e.g. 1024 would be 1MB email limit.
To limit ALL emails across the MTA, both incoming and outgoing, change the BLOCK_LIMIT option.dat variable:
"Places an absolute limit on the size, in blocks, of any message that may be sent or received with the MTA. Any message exceeding this size is rejected. By default, the MTA
imposes no size limits. Note that the blocklimit channel keyword can be used to impose limits on a per-channel basis. The size in bytes of a block is specified with the BLOCK_SIZE option."

Setting a Default Organisation Message Size Limit and a Higher Limit on an Individual Mailbox

Ok. So here's the problem. I've read all the articles on setting message size limits for Organisation, Transport Send Connectors, Transport Receive Connectors, setting precedence, etc., but they don't detail how to solve this problem.
One person in our organisation is to get a raised message size limit for sending and receiving internally and externally. I've already set up limits on the Organisation Transport Global Settings, Send Connectors, Receive Connectors, etc. So,
as this individual requires a higher limit, I've raised the limits on their mailbox, and the aforementioned connector settings, etc., except the
Organisation Configuration / Hub Transport / Global Settings / Transport Settings / Maximum Receive
and Send Sizes. The theory is that I can keep these two values at the original lower setting as these are overridden by the individual's new, higher, mailbox settings, but they will continue to act as the default for other existing mailboxes
and newly created mailboxes. Right ? Wrong! For the individual's mailbox, this will only raise the limit for messages sent internally (not to or from external email addresses).
Now, I could change all existing mailboxes to have the old default lower limit using a PowerShell / EMS command, but this wouldn't work either. Newly created mailboxes will still default to the new larger limit. Most of our mailbox creation is
scripted, though some are created manually. I don't want to alter the script and inform the admins as this is too much work and admins will forget about the new limits. TBH, I'll probably forget about the new limits. That's just a messy inefficient
approach. What I want is to set a new default for message size limits, with the original low limits. I.e., a setting that applies to existing mailboxes with no explicit message size limits set, and also newly created mailboxes, but not any mailbox
with an explicitly specified higher message size limit. Any mailbox with explicitly specified higher limits should be able to send larger messages both internally
and externally. Can anyone help ? Like I said, I've already read the articles so I don't need links to these thanks. I'm more looking to people who have done this kind of thing already.
BTW, we are using Exchange 2007 SP3. It has a mailbox server Single Copy Cluster (SCC) with two nodes. It also has two Client Access / Hub Transport servers. Just so you know ;-)

Hi huddie71,
Thank you for your question.
I've raised the limits on their mailbox, and the aforementioned connector settings, etc.,
except the Organization Configuration / Hub Transport / Global Settings / Transport Settings / Maximum Receive and Send Sizes.
By my understand, we could modify the global settings by the following path:
Organization Configuration / Hub Transport / Global Settings / Transport Settings / Maximum Receive and Send Sizes.
Because it will work on existed user and new user without explicit message size limits sets.
If there are any questions regarding this issue, please be free to let me know.
Best Regard,
Jim
Hi Jim-Xu. That would result in everyone getting an increased limit. I only want one person to have an increased limit. See the 2nd paragraph in my original post.

How to limit mail size of outgoing messages per domain/user

Hello,
i want to limit the size of a mail a user can send. For inbound mail there are attributes in the directory service: mailDomainMsgMaxBlocks and mailMsgMaxBlocks.
But these limitations only enforce the size of incoming mail.
I've read the messaging server admin guide but all i could find out is that i could limit the size of outgoing mail via a channel.
For me this solution ist not granular enough. I want to set the outgoing mail size limit per user. Furthermore i don't know the impact of configuring 200+ channels for enforcing individual outgoing mail size limits per hosted domain.
Does anybody know a solution for this problem? Maybe i've read over something. Or can anybody tell me the performance impact of 200+ channels at least?
Thank you very much,

JES 2005Q1, Solaris10, V440

Hi jay_plesset,
thanks a lot for your clarifications.
Why would you need 200 channels? That sounds like a
very strange setup. Setting outbound max size per
user sounds like a very unusual demand, too.Let me explain: I got several departments who control their email settings in the messaging server via a webapp. So they can add, delete and modify users. They can manage mailing lists and so on. It's really a cool tool :-) I want this thing to be as granular as an own mailserver for the department would be. So it would be cool when the webapp writes an attribute like maxMsgBlocks in the DS and the thing is done.
I don't understand why you guys could do the stuff for inbound but not for outbound. Is there a technical reason or is it just because it seems strange? :-)
If you REALLY need something like that, 200 channels
would need a POOL of at least 200 jobs in order to
reliably run, and that's likely to need lots of
system memory.I think that's not the way i want to go.
Consider a custom channel, or something like that,
that does an LDAP lookup for setting message size on
sending. You'd need to enforce smtp authentication,
so you know who your messages are coming from, first,
and then you could proceed from there. This is not a
trivial setup.Sounds interesting. Any documentation hints for custom channels?
Thanks again for your reply,
