Corrupt Attachments in SmarterMail 12.3
Problem reported by csoft - 12/2/2014 at 3:40 PM
Not A Problem
We've had issues with users getting corrupted attachments with SmarterMail 12.3 (jpg and pdf) when uploaded through the web client. Anyone else had this problem? Any solutions?

UPDATE: The corruption actually happens during the download of attachments, not during the upload. ZIP is also corrupted if clicking download all.

Firefox had some issues with this a week or so ago. Make sure your browsers are up to date.

Is the user pressing send email from the web interface before the attachment completes the upload process? We have experienced this when uploading large pdf attachments. The file is incomplete for the download process.

Has this been fixed, I'm running 13.3 and my faxes are coming in to Windows server through a modem and 
emailed to me as a PDF and corrupt every time.
If I view them on the fax server they seem to be fine.

Just updated to the latest 13.x. I have the same problem with PDF attachments, all browsers tested (IE, FF, Chrome). I can forward the PDF attachment to Gmail and can open the PDF without a problem.

This is a webclient issue. I am able to open the corrupt PDF via Outlook.

I just switched from IIS 6.0 to the built in web server and the PDF opened without a problem. Something isn't right with IIS.

I tried this and it didn't work, it seems like the attachment is corrupt upon retrieval. I think there is a problem with SM.

Wilson, I found this KB article. I applied this fix and it didn't help my setup, perhaps it will help your setup.
http://portal.smartertools.com/kb/a2895/attachment-missing-corrupt.aspx?KBSearchID=636850 Applies to SmarterMail 8.x - 13.x
When running SmarterMail in VMware attachments may randomly go missing or become corrupt.
These issues can be seen when using VMware's E1000E adapter (VMWare's default). To resolve these issues you'll simply need to create a new adapter in VMware using "VMXET" (VMware's own virtual NIC driver with no physical counterpart). Once this is complete, these attachment issues should be resolved.

Thanks for the tip, not sure if this apply to me, I'm running Xenserver and the only attachments are arriving corrupt are FAX, other PDFs attachments I get no problem. It's strange why only the FAX.

Sorry I didn't get back to you sooner on this. the issue was with smartermail engin, Smartertools corrected the problem and sent me a new smartermail.exe, I reinstalled and the problem is fixed.
I assumed this corrected exe is automatically released as an update but I guess not.

Hey Matt, I have tested this issue with Chrome, FF and IE 11. All present the same problem with PDF attachments using IIS 6.0.

Have you tried different PDF's?
For further help you probably want to make a support ticket that way we can look further into the issue and get it fixed. If it's found to be a bug in SmarterMail your ticket will be refunded.

Hi Guys, not sure if you missed my post above or I wasn't clear on the fix. This was a bug and ST fixed it and sent me the fixed install file.
I guess you have to ask Smarter Tools for it.

Wilson all fixes should be incorporated into all future releases. That fix should be in this version as it was fixed a while ago.

Matt, All PDFs are a problem, however, if I use IIS 6.0 the PDF is corrupt. If I use the built in SmarterMail web service the PDF is fine (same PDF in the same email - I don't have to resend the email).

Sounds like you are running under Server 2003 and you must upgrade to server 2008 or server 2012 no later than 14 July, 2015, when all support for Server 2003 ends - unceremoniously, at midnight.
 
IIS 6.0 is only viable for another two months as it sunsets on 14 July, 2015 - at the same time that Server 2003 quits being supported by Microsoft

Bruce, Thanks for the post. I am aware of Windows 2003 is EOL this year. This doesn't mean Windows 2003 will suddenly stop working on July 14th. SmarterTools supports SmarterMail on Windows 2003 so all features of SmarterMail should work with or without Microsoft support.

All new versions of SmarterMail will require .NET 4.5, which does not run on Server 2003.
 
Additionally, all of the antivirus vendors are ending their support for Server 2003 on 14 July, at midnight - the antivirus protection will, literally, quit working.
 
If you are running server 2003, you need to upgrade ASAP - before midnight on 14 July, 2015

I do not think it is accurate that all antivirus vendor are ending support coinciding with Misrosoft's date. They said the same myth for windows XP and I have XP boxes still working fine with working antivirus no problem.

The EOL of Server 2003 is a coordinated effort, led by Microsoft, to quickly move users off of the server operating system.

Most of the AV vendors have indicated, in articles referencing the Server 2003 EOL, that they will pull the plug on their support simultaneously with Microsoft's end of life for Server 2003.
 
Those who still have Server 2003 running are receiving regular notifications from installed product that it will sunset with the scheduled product "dead" date.
 
The end of life for Server 2003 is not something to be ignored and anyone who is running Server 2003 needs to make immediate plans to upgrade to Server 2008 or Server 2012.

I have a few 2003 servers running AVG antivirus and they work just fine with zero notification about EOL.

For many organizations, the security concerns in Server 2003 are minimal.  Border security is handled elsewhere, and modern antivirus and antispam programs take care of most, if not all, threats. Security certificates may or may not be an issue in these installations, and might demand a server update, but this should be on a case by case basis, just as are many other considerations.
 
The question sometimes boils down to: The application software running on these boxes, and if it can be kept current, and any other mandatory security considerations, such as HIPAA rules, that might be in play.
 
So indeed, new versions of SmarterMail would certainly require an update to later Windows server versions. But one size, as usual, does not fit all.
 
I recall companies running Novell Netware 3.x, for example, for years after it was obsolete. Indeed, I have one client with a FoxPro DOS app that is STILL running it (!).

Update: After posting, I explored a different approach since I realized the content was the same and the only change was the download method. I found this article: forums.anandtech.com/showthread.php?t=2248960 which had a resolution for this issue.

I disabled HTTP compression in IIS and can now open the downloaded PDF without error.
