Couldn’t Send/Receive Emails with Attachments Greater than ~3MB

So awhile back, I hit some weird problem with my email. I was trying to schedule weekly backups of my websites and email them to me. My HD-Trailers.net backups worked fine, but my Krunk4Ever.com backups were giving me problems. The email would come through and the size would be correct (~5MB), but the email didn’t have any attachments. I tried copying it over to another directory, and the size shrinks down to a few KB.

Thinking it might that my Krunk4Ever.com mail server has some attachment size restriction, I tried sending it to my GMail account and the same thing occurs. Do note, I have GMail mapped in Outlook 2003 as a IMAP folder. I see a 5MB email, but no attachment listed. For the time being, I concluded that someone’s restricting the attachment size and I would just go and backup manually once a week.

However, another problem occurred when I was trying to share a video with someone. It was a 3.12MB video and Outlook would just not send it. It kept on giving me the following error:

Task ‘Krunk4Ever – Sending’ reported error (0x800CCC13) : ‘Unable to connect to the network. Check your network connection or modem.’

Searching for that code resulted in some winsock error, but that didn’t get me anywhere. I decided to shoot DreamHost an email and their reply was:

Our email supports up to 40 megabytes for outgoing and incoming emails. Our webmail; however, is limited to smaller file-sizes If you need to send-receive large attachments you would need to install your own custom webmail and possibly PHP or use a full-featured email client such as outlook or thunderbird. Please let me know if you have any additional questions.

It turns out not all large attachments were blocked. A few 5MB files have gotten through before, and if I just keep trying, eventually they make it through. I went to GMail (web based) and searched for previous emails where I had sent my backup databases and they were indeed okay and I could see the attachment fine. That led me to a preliminary belief that Outlook or IMAP had some sort of attachment size restriction. Testing it out in Thunderbird was something I had planned to try next, but didn’t really get around to it.

Today, I was trying to email my work email some logs that some Vista people wanted and I hit the same darn problem. I eventually uploaded it via OWA (Outlook Web Access), but then that got me angry. So I began searching around for other people who have gotten the 0x800CCC13 error, but a quick skim didn’t result in anything useful. There were a lot of mentions of firewall and antivirus, but think that my regular email came through fine, I didn’t see how a firewall or antivirus would be acting up…

Then I tried disabling my antivirus and resent the large email. Guess what, it WORKED! !@%$!$#%#!@%@%#!@% The antivirus software I use on my main box is CA (Computer Associates) eTrust, which is what we use at work. Given that Microsoft is a software company and they mandate us to use eTrust, I just assumed it was good enough. eTrust is actually rather nice. It’s small, lightweight, and pretty nice on the system resources.

So I went into eTrust to see if I could configure this weird email problem I was getting. I could not find a single email option to configure. It does mention it scans incoming and outgoing emails, but there was nothing to configure that was email based. The only possible solution I saw was to add Outlook to the exclude list which I didn’t want to do.

I eventually decided to uninstall eTrust and went with AVG which I’ve installed on most of my other machines, and my emails with large attachments appear to be working fine.

One thought on “Couldn’t Send/Receive Emails with Attachments Greater than ~3MB

  1. I has a similar problem with Outlook 2007, the same error, but e-mail limit was about 200 KB. In log was error ID8 from crypt32. Email server – sendmail for Linux.
    The reason – damaged root sertificates in Windows XP. I install SP3 for XP – problem was no change. I download the update from Microsoft and the problem is disapear.
