Restricting mails to a particular domain

Hello,
I am using JavaMail API and have a small requirement. I have to restrict my outgoing mails to only to a particular domain. I mean the mails that i send should go successfully only if the domain is "[email protected].Even if the users of my application types someother domain like yahoo.com or anything else, the mails shouldn't go. I want to restrict the users to send mails to only our company domain. Is that possible, any method available to set it so?
Please help.
Thanks in advance.

If you control the mail server you're using, you
can probably configure it to limit messages to
your domain.
There's nothing in JavaMail to help you with this.
If you can't configure your mail server, you'll have
to implement the limit in your application.

Can Mail block all incoming mail from a particular domain?

Can Mail be configured to block all incoming mail from a particular domain? I'd rather it be sent to the bit bucket than sent to a spam folder.

Yes, go in to your rules and set it up for a folder of your choosing. Click on the mail menu item then select preferences and then click on rules.

Could you please advice the resolution?

Hi Bhanu Prakash K,
Did you mean that send email to an external domain email account slowly via MVC application? However, when
send to an internal email account, will work
immediately?
Based on your description, this issue seems to be more related to MVC application. I suggest you should post
this question in ASP.NET Model-View-Controller (MVC) Forum. I believe we will get a better assistance there.
If any update or anything I misunderstand, please don't hesitate to let me know.

How can i block outgoing mails to particular domain

I have just set a mac mini with snow leopard server . Configured mail in it . I want to block the outgoing mails to some particular domain or all domains other than my server domain .
please help

Hi Fritz:
Your English is FAR better than my Deutsch (Ich bin ein Wisconsonite). I can barely ask for the train to Zermatt (one of my favorite places on Earth).
Anyway, I think I understand your question. If you mean is there a way to stop the recipient of an E-mail from actually getting it (after you sent it), the answer is no (in Apple's Mail application). Entourage (a Microsoft application) is a good program. As I recall (I used Outlook years ago in my corporate world) the Microsoft mail applications have a feature to "un-send" E-mail). However, I think that only worked if the mail was sent to someone on the same network. You could not retrieve mail from someone outside your own network.

Outbound Mail Flow (bypass EOP for particular Domain)

We have on-premises Exchange 2007/2013 Servers. And have hosted mail protection (Exchange Online Protection). Side note - 2007 servers being retired soon. Our mail is routed via EOP etc.
One of our members of staff is starting to use a goverment secure mail service. This involves setting up a POP3 account on the users Outlook.
It has to be configured to send over SMTP using SSL.
Getting an error saying the connection encryption type is not supported when doing the send test (receives OK).
Upon checking with the Support for the service, routing mail through Office365 will not work. We need to route the mail directly.
This is probably a newbie question but how do I do that? Do I create a new send connector and define the particular domain in there? would I use my ISPs smart host address?
It's just for sending mail, as I say the POP3 account is receiving OK using the POP3 settings.
Thanks in advance.

Yes, define a send connector for the recipients address SMTP scope.
You wouldnt need to smarthost necessarily, you could simply set it to use the MX record.

TS3276 I have issues receiving e-mails from a particular sender. I can send e-mails to them but they can't send to me. They get "None of your e-mail accounts cold send to this recipient"

Like stated above. I cannot receive e-mails from a particular e-mail address. I can send to them but they can't send to me.

Have you contacted your email provider and asked if for some reason that sender or domain has been blacklisted?

Creation of transport rule to send all external mails through a particular server for a specific user..

HI,
In our Organisation We have a question, is there any possibility to create a transport rule for sending all external mails through a particular server by a specific user.
in our organisation we have exchange 2007 one mailbox server and two hub transport servers...and we are using symantic gate way..

Hi,
Based on my knowledge, we can use the following transport rule to make that except with one user, other users cannot send outbound external emails:
And I’m afraid that there is no Exchange feature to make one specific HUB server rout all external emails.
Because if a Send connector is configured to send messages to an external domain, any Hub Transport server in the organization will route a message for that domain to a source server for that connector to be relayed to the destination domain.
If you have any question, please feel free to let me know.
Thanks,

Mail to a specific domain not being delivered

We are able to send/receive emails to external domains and everything seems to be fine with our exchange server except when we try to send mails to this one domain @ ju.ahg.com.sa
Upon troubleshooting further, we came to know this domain doesn't have a valid MX record.
Yet the mails to this domain get delivered by gmail and other email services.
If we use the SMTPDIAG tool, below is the output.
Note that when its done from our domain, it gives error, when done from gmail ...its success!
How can we fix this issue?

You are right, when I looked up using MXTOOLBOX.com ; this domain seems to have a valid MX record, but no valid A record. Would that be the cause?
Also, I tried through the command line, and it seems my DNS server is unable to resolve, so I am not even getting the MX record.
I have 2 DNS servers , how can I try these commands to use the other DNS server ;
as I tried on both servers, It gives the name of the first server only and says it can't find this domain: Non-existent domain.

How to Restrict printing the document using IRM for a Single Document?Allow printing for some documents and restrict the printing for particular documents in same document library?

Can we able to Configure the IRM in Document Level in SharePoint Document libraries?
The document library contains multiple document sets , Can we restrict the printing according to document sets? Allow printing for some documents and restrict the printing for particular documents in same document library
Is this possible?Please suggest.

Yes, that can be done. But note that all administrators will have the same right to print, so you need to make sure the users are not administrators. You can include a macro to disable printing, but if the users disable macro, they can print the documents.
Hence, there is no foolproof way to prevent printing documents. If you still need a foolproof security, PDF format provides password based security (viewing doesn't require a password) that can be implemented to prevent the document from printing,
which doesn't require any special scripts and is tough.

How to send a mail on a particular date

my server is IIS and i am using java servlets and java mail api.

As far as I know there is no method in JavaMail for sending a message on a particular date.
However you can use the Java.util.Timer and java.util.TimerTask class to do this.
In the class that you send your message from
public class SendMessage extends TimerTask{
public void run(){
//send message here
TimerTask implements Runnable so a thread can be created here.
To call the thread:
public class CallMessage{
public static void mail(String args[]){
SendMessage sm = new SendMessage();
Timer timer = new Timer();
timer.schedule(sm, 10000, 10000)
//wait for 10 seconds and repeat in 10 seconds
There are a number of different schedule methods available for whatever you need to do.
Hope this helps!

Picking mails from a particular sender using mail sender adapter

Hi Everyone,
I want to create a scenario in which i want to pick mails from a particular sender and send it to XI.
I don't want all the unread mails to be sent to XI but only those belonging from a particular sender.
How should i configure the mail sender adapter to achieve the same.
Thanks and Regards
Rahul Nawale

Hi,
there are two ways to do that:
not standard:
create a java proxy which will check your maibox for mails
from only one particular sender and then send messages
to the xi
more standard:
create a new accound and redirect your mails from a particular sender from the main mailbox to this new one
and poll from this new one only...
this way you'll be able to use atandard mail adapter
with no changes at all

michal

Problem going to one particular domain

I have a problem going to one particular domain, sanjoseca.gov. Any websites starting with http://www.sanjoseca.gov/ do not load. I've tried enptying the cache, but that doesn't work. I have no problem loading any other domain. I used to be able to access the city's sites without problem up to a couple of seeks ago, but since then, I can't load. I tried using Firefox, but can't with it, either. The city says they have no problems with their site and a city employee went onto the internet while I was talking with her and had no problem. Any suggestions?

jwsapp-
That site loads fine for me.
I would quit Safari and delete all cookies having to do with that site --
or dump them all. Safari Prefs>Security>Cookies>Show All Cookies.
Also, make sure you've cleared your Safari Cache & History.
It also might be helpful to trash your icons folder:
Your HOME (YourName) folder>Library>Safari>Icons.
Restart Safari.
Do those & report back, OK.
