    Default Attachments Getting Munged

    I'm having an irregular issue with Zimbra and file attachments.

    I'm running v3.1 on RHEL 4 (Twin 3Ghz Processors w/1Gb RAM)

    Occassionally, when attachments are sent, they are being corrupted. I'm convinced it's being done by my Zimbra server as I've been able to replicate it with a specific message I have with attachments. I have been able to successfully receive this same message at my work email and at a gmail account without problems with the attachments.

    The errors in my /var/log/zimbra.log file are:

    Apr 21 10:49:45 email amavis[25617]: (25617-01) WARN: MIME::Parser error: part did not end with expected boundary
    Apr 21 10:49:46 email amavis[25617]: (25617-01) spam_scan: not wasting time on SA, message longer than 65536 bytes: 1566+79606
    Apr 21 10:49:46 email amavis[25617]: (25617-01) BAD HEADER from <username@organization.com>: MIME error: error: part did not end with expected boundary

    This behavior is seen regardless of whether I'm using the web frontend to Zimbra or using Thunderbird to connect via IMAP.

    Any ideas?

    Thanks!

    can you attach (or pm) the full mime message here?

    Yes, I can. But, I'm not quite sure what you want me to attach. Could you be a bit more specific? I could attach the actual email or I could attach the full log for the message.

    But, I suspect you're wanting something different. Sorry if your request is clear as a bell and I'm not getting it

    no problem. in zimbra, you can right-click on a message in the list and select "Show original" to get the full mime-encoded message. other mail programs will also usually have ways to view this.

    We want the entire thing. Please save it to a file. zip the file and attach using the 'Manage Attachments' option. Do not just copy/paste the data in as it will lose some formatting.

    Default Can't See TIF Attachments

    I'm having a similar issue - our fax server attaches .tif files in a multipart/fax-message format -- the message shows a paper clip but when you open it there is no attachment.

    Attached is the full file of an example.

    This appears to be a bad MIME message. Claims to be multipart but is just one part. I'd recommend you file a bug in bugzilla and attach this message.

    Any other thoughts on this issue? Today I received an email with two attachments. Both Word documents. One document came through fine. The other one did not.

    It's getting to the point where I am seriously contemplating shutting off my Zimbra server as I can't trust that the attachments people are sending me are going to make it through.

    Can you reproduce it with the one that did not come thought? Were both attachments the same size? Sent from the same mail client on the same mail path? What was wrong with the one that didn't come through or did you not get it at all? If so how did you know you didn't get it?
