Block File Attachment Upload for Gmail & Hotmail

Hi,
I need Block File Attachment Upload in the followings applications: Gmail and Hotmail.
These appliacations use ports 80 and 443. Ironport has this option but only for "Access policies"  and I need apply also in the "Decryption policies"
Access policies has Applications option.
But Decryption Policies don present this option...
who can help me with this question ?
Regards,
YMD

YMD,
I am not exactly clear on what you are asking - with both 'Enable Decryption for enhanced Visibilty and Control' and blocking the webmail file upload/download in Access policies, does that resolve the issue for you?
As for *how* it works, I think you are effectively talking apples and oranges, since the Access policy deals with how things are accessed/no accessed (file upload/download blocked/allowed), where the Decyption policy isn't 'access' so much as deeper traffic inspection.  They are two separate things...  if that makes sense.

  • File Attachment Upload - submit error in Ipad

    Hi,
    I created a webform for my staff to log visits to physician's offices.  The form includes a file attach button which works great from a PC.
    I downloaded ICab browser app for ipad, and it actually lets me choose file from ipad photo stream/camera roll.  However, when I hit "SUBMIT" button on form, they get an error that reads:  "An error has occurred.  There was an error communicating with the server.   Please try again later."
    Any ideas as to why I am getting this error when submitting form with file attachment from Ipad?
    Thanks !

  • Can not modify a file after attaching it in gmail

    I am running firefox 9.0.1 on windows xp pro and after I drag and drop a file to upload in gmail, the file cannot be deleted until I close firefox. I'm on a work computer so I can't update to the latest version of FF. This has been asked before but for previous versions of FF. Also the mail has been sent 10 minutes ago and I still can't delete the file. So the newly composed email has been closed

    (You should talk to your IT department about the very real security risks of running such an old version of Firefox, and have them at least switch you to the Enterprise release of Firefox)
    Try to follow the directions at [[Websites look wrong or appear differently than they should]], they may help with these issues.

  • How is a file attachment stored in database?

    Hi all~~
    I am developping an email application(web based) using Javamail. I need to store the attachment together with the relevant email messages in the database. Is that correct that I add an attribute called ATTACHMENT in the entity which stores the file attachment uploaded by users? If so, is the datatype of ATTACHMENT called OBJECT?
    This question confused me for more than a week already. I can send an email with the attachment which I wrote the path of the file in code, but I can't store it in the database.
    Your advice is appreciated!! Thank you!

    Hi,
    Oracle stores the BOM in basically 2 tables BOM_BILL_OF_MATERIALS and BOM_INVENTORY_COMPONENTS.
    The simplest way to explode the BOM in Oracle is to use the BOMPEXPL (BOM Exploder) package.
    Hope this helps.

  • IMAP. Two Leopard Macs. 1st Mac sees file attachment 2nd Mac doesn't

    I use two Mac computers both on 10.5.2, each running Apple Mail 3.2 to access Gmail's IMAP.
    Worked well for ages, but recently, in one computer, I sent an email with a very large 3MB file attachment, and then transferred it to a folder. That was then reflected in Gmail's IMAP interface. Hence, as far as Gmail is concerned, the file attachment and email are there.
    But when I used the 2nd Mac to download the same email, the email is there, but no file attachment.
    When I open the particular email, there's an error message at the top of the email:
    Apple-Mail-9-1026228142
    Content-Type: text/plan; charset=WINDOWS-1252; format=flowed; delsp=yes
    Content- Transfer-Encoding: quoted-printable
    I've never seen that before.
    Also, in the 2nd Mac, in Apple Mail, there is no paper clip icon that is usually associated with a file attachment.
    Even stranger: A few days later, I initially used the 2nd Mac to download an email with a file attachment. So the email and file attachment are on the 2nd Mac. I verify that the email+file attachment are on Gmail's IMAP web interface.
    The strange thing, however, is that the 1st Mac now only seems the same email, but no file attachment.
    It almost seems as if whichever Mac I first use (either the 1st or 2nd Mac) to download an email with file attachment, that initial Mac sees the attachment. But subsequently, when the other of the Macs downloads the same attachment, it does not have the attachment.
    As said, Gmail's webmail IMAP indicates the attachment is there.
    Any ideas?

    I figured it out. I had been connecting to my router with Ethernet AND Airport (both were turned on in my Network preferences, and both had a green-light status of 'connected'). Don't know why that would have affected it, but when I turned OFF the airport connection everything was instantaneously corrected.

  • Trying to find answers for the question "Why is this file type blocked from being uploaded into SharePoint"

    At least once a month - sometimes much more frequently - I get calls from users asking why the file extension they "need" to upload to SharePoint is blocked.
    Most recently, it was a Microsoft Access database that the user was attempting to upload to a document library. Before that, it was a shortcut link (*.url). And so on.
    Is there a reference document which goes over the reasons why specific file types are blocked?
    Thanks!

    Each blocked file format has it's own reasons for not being allowed to be stored on a SharePoint library.
    Some of them are blocked because they would be processed by SharePoint Servers during the upload/download sequences, thus, possibly corrupting the system ( like dll files ). Others would cause Crawl to break ( url files ).
    The Access database files are blocked for two valid reasons. First, because saving "live" to those files using Windows explorer window ( WebDAV ) doesn't work. Second because SharePoint product managers want us to use SharePoint lists instead.
    And it does makes sense.
    If you're in the middle of a migration from file servers to a SharePoint solution, your people could use these situations to stop and think about it for a little:
    Really ? Now that we have SharePoint, couldn't we do things a little bit differently ?

  • How to provide file attachment  service (file upload)

    i have to provide the attachment service to the application .
    the application must successfully upload the local file and send it to the destination.
    this application is like any other email service ex. yahoo , hotmail ... which provides attachment service apart from email.
    From the html form which have fields for file and when user clicks on submit then the program must send or store the file in destination user' account.
    we are using html , jsp , servlet , java , j2ee.
    If anyone know please help me in this issue.

    There are several steps:
    1> Change the form's encode attribute to multipart-formdata
    2> For each file to upload, create an <input> tag with the type attribute set to "file"
    3> Within your Servlet, you need to detect the content-type and content-encoding from the request. If you recognize it as multipart-formdata, you will be receiving arbitrary binary data and need to go to step 4
    4> Buy an Oreilly book so you can get a copy of his multipart form reader classes. These will automatically parse the HTTP body into its constituent parts, of which zero to many parts may be file data (depending on your form)
    If you don't want to buy the Oreilly book, there are some code snippits out on the web. Or you can read the HTTP RFC at www.w3c.org and implement it yourself. (Not all that tough).

  • How do I enable uploading via gmail as I have originally blocked this?

    Windows 7

    I don't know how you could block file uploading in GMail, but here's one thing to check. Right-click the page and choose View Page Info. Then click Permissions and scan down the list for anything that is not set to Use Default. If you change those back and reload the page, does it work again?

  • Slow attachment upload with Exchange Web Services (Outlook 2011 for Mac?)

    We're experiencing slow attachment upload with Exchange Web Services versus MAPI, OWA, and Outlook Anywhere.  I'm not totally certain that it is Exchange Web Services or specifically Outlook 2011 for Mac.  I attempted to test with the Mac Mail
    App, but it makes it difficult to tell when the attachment has been uploaded and the file has been sent.  Here's what we're seeing (10mb file):
    MAPI / RPC/HTTPS / OWA: 10-15 seconds upload time
    Exchange Web Services (Outlook 2011 for Mac): 60-90 seconds upload time
    Thoughts? Any idea why we would see such a drastic difference in attachment upload time?  Any way to prove definitively that it is Exchange Web Services vs. Outlook 2011 for Mac?  We've tried it from multiple locations with multiple different machines,
    and although the upload times vary (some locations have more bandwidth etc) the ratios remain similar.

     
    Hi ,
    Does all the user occurred the issue ?
    If only special user, I recommend you do the following steps and test:
    1.Remove and re-add the email account and check if this helps to resolve the issue.
    To remove and add the email accounts:
    Open Outlook > GO to Tools > Accounts > Click on "Minus" symbol to remove and "Plus" to add an Email account.
    2.Creating a new user profile:

    You can also post it on Office for MAC forum  to get special support about the difference between Outlook and Outlook for MAC.

  • Export Table to flat file and upload to FTP server for external vendor

    I have done some extensive searches on the forums and I think I have an idea but really need some help. Basically have a table that needs to be exported to a flat file and uploaded to a FTP server so that our vendor can get the data Monday-Saturday and automated by sysdate. This data is used to produce daily letters that go out to customers.
    After doing some searching I came across the UTL_FILE package and reading more into this right now but I am not sure if it is what I should be using to create the file.
    I am using TOAD right now and can see how to do it manually however really need the file to create itself and send automatically at 6 am Monday - Saturday with the date at the end of the file name making it a unique file for each day.
    Thanks in advance for all of your help.

    As Justin and others have mentioned I wrote [XUTL_FTP|http://www.chrispoole.co.uk/apps/xutlftp.htm] so you wont find it in the Oracle documentation. It's pure PL/SQL and uses UTL_TCP and implements an integrated PL/SQL FTP client / API. One of it's many overloaded procedures FTP's the contents of a refcursor straight to a FTP server of your choice, meaning no intervening file is required. Since it is pure PL/SQL, it is trivial to schedule using DBMS_JOB/DBMS_SCHEDULER.
    Any questions just ask.

  • Peformance Turning for File Download / Upload with Enabled SharePoint Audit

    Greetings all, may I ask your help for Peformance Issues?
    Background:
    I tried to create a ASP.NET Web Page to download/upload/list SharePoint file and deployed to IIS website in same application server (will NOT use web part as some users are NOT allowed to direct access confidential workspace)
    Besides, for Audit Log record purpose, the page will impersonate (without password) the logged in user:
    SPUserToken userToken = web.AllUsers[user].UserToken;
    SPSite s = new SPSite(siteStr, userToken);
    For File Listing, the web service can provide fast response, and we are using service A/C for connection (as no auting for listing, but require audit for file download upload)
    Several implemeation options tested for File Downloiad / Upload, but issues occured and finding listed below:
    Issues
    1) SharePoint Object Model
    When I open Site (using new SPSite), it's too slow to respond. (under 1s for all operations, but require 10~50s for open SPSIte. e.g.
    using(SPSite s = new SPSite(siteStr) //50s
    How can I download/upload file without open SPSite object (using SharePoint object model, but user token should be kept to allow SHarePoint identifiy user actions. e.g. Updated by Tom, NOT system administrator)?
    2) SharePoint default web service
    For file download, I tried to use SharePoint Web Service for download file, it's quick but how can SharePoint record the audit log to downloaded user, and not service A/C? ( e.g. View by Tom, NOT system administrator)
    With Windows SSO solution, please note system should NOT prompt to ask user password for use impersonation
    3) HTTP Request API (for file download)
    As mentioned in point 2, if the system cannot get password from user, SharePoint also recorded service A/C in audit log... ><
    Thank you for your kine attention.

    Thank you for prompt response, please find my reply with Underline:
    Hi,
    Maybe I'm not quite clear about the architecture you have now.
    Is your asp.net application deployed in separate IIS site but in the same physical server as SharePoint?
    Yes
    "we are using service A/C for connection", can you please explain the 'A/C'?
    Domain User, Local Admin and also SharePoint Service Admin A/C
    Opening SPSite is relatively slower but shouldn't take 50 sec. However it depends on your server hardware configuration. You should meet the minimum hardware requirements for SharePoint.
    Assigned double resources based on minimum hardware requirements.
    For details, 50s is the load test result. But for other SharePoint operation, it takes around/under 3s reponse time.
    Are you using SharePoint Audit log? Exactly If so then why don't you just put the hyperlink to the documents in your asp.net page. User maybe have to login once in SharePoint site but
    it depends on your security architecture. For example if both of your sites in local intranet and you are using windows integrated authentication, SSO will work automatically  User is NOT allowed
    to access SharePoint site/server (not implemented for sepreate server yet, as performance issues occured for
    separate site in same server)  directly from Internet, the
    middle server with web interface created for user request.
    Whatever I understands gives me the feeling that you download the file using HTTPWebRequest C# class. However regarding security it depends on how authentication is setup in asp.net web site and in sharepoint. If both site uses windows integrated security
    and they are in the same server, you can use the following code snippet:
    using (WebClient webClient = new WebClient())
    webClient.Credentials = System.Net.CredentialCache.DefaultNetworkCredentials;
    webClient.DownloadFile("file ur in sharepoint", "download directory");
    Thanks, will try and reply later
    But still, as I've mentioned, not quite clear about the whole architecture.
    A) Request Handling
    1) User use browser to request file listing and/or download file (hereafter called: File Download Request) from custom ASP.NET page (Let's say In Server 1, IIS 1)
    2) ASP.NET　page  or File Handler ashx (Server 1, IIS 1) call custom web service, SharePoint deault/OOTB web service or using SharePoint Object Model to access SharePoint Document Library (in Server 1,
    IIS 2)
    3) Both SharePoint and IIS Web Site
    (Server 1, IIS 1 & IIS2) using the same service A/C
    4) The web service , File Handler return file obeject to IIS1
    5) IIS 1 reply File Download Request to user
    B) Application Architecture (In testing environment)
    1) no load balancing
    2) 1 DB server (Server 2)
    3) 1 Application Server (with IIS 1 - ASP.NET, IIS 2, SharePoint Web Site with default SharePoint Web Service, IIS 3 SharePoint Admin Site & IIS 4 Custom SharePoint Web Service)
    4) Sepreate AD Server (Server 3)

  • DMS - File attached for FI posted document

    Hi All,
    I am new for DMS .
    My requirement is - we have web application in .net  . Vendor update entry in web application , attached some file with that page and go to submit .
    It comes in SAP through proxy and posting in FI has been done .
    But the file attached in .net application is stored in .net application server .
    So now requirement is when we open posted document in SAP we need that file attached with posted document (available in GOS for that t-Code) .
    My question is -
    1 - how we create entry in DMS dynamically ( we got posting confirmation in SAP through proxy and we got that file in SAP application server through file transfer ) . But how to entry maintain in DMS (we have multiple document for single posted document ). Even I know how to create document type for DMS n basic thing of DMS .But I need algo . 
    2-  How that entry link maintain to that FI T-Code . 
    Thanks to all .
    Regards,
    Alter

    Hi Ravi,
    you need to customize in OAC3 the Documenttyp link to FI Object.
    e.g
    ObjectType      Doc.type   Status Cont. Rep. Link  Doc.class      Ret.per.
    BKPF               #ZXYDOC#      X      C1    TOA01      PDF              180
    From your Server you need to call am FM (something like ALINK_CREATE_ASYNCHRON_META" on your SAP System via RFC to save the File after you created the Object.
    regards

  • File size limit for webdav upload

    Dear Experts,
    we set up what we thought to be a restriction of the file size allowed for upload. We did this in the portal via
    System administration --> system configuration --> Knowledge Management --> Protocols --> WebDav --> Max WebDAV request size: 15728640 bytes.
    We would have expected that to not allow us uploading any files larger than 15 MB. Turns out we were wrong and it does not work. Here is a http-trace of an upload of a 21 MB file.

    Hi Michael,
    This cannot be possible in portal but you can upload the max size file through portal drive or webdev . Through portal drive you can upload 50mb or any format file size you can upload through portal but portal you cannot upload you can get the message of file uploading failure or connectivity issues like these messgae appears at every interval so go through the portal drive or webdev.
    But best option for uploading huge file size is Portal drive. This will helpful for you.
