[Dovecot] dovecot forward multipart problem
Hi,
I experience problems everytime i forward a mail (basically, when forwarding an email containing an attachement). I'm using thunderbird (it does the same with outlook clients) with the forward parameter "as attachement" instead of "inline". (Using the inline parameters works fine). When i forward a mail with attachements (eg a jpeg file), the attachements file is displayed in base64 instead, and is impossible to detach/save.
I'm using dovecot 1.0.rc22-1 (debian package) on debian etch, x86 SMP box with maildir format on a ext3 partition. I'm using postfix currently 2.3.4-3, i have tried different version of dovecot (from rc16 i think) and postfix (from 2.2.?) and i suspect the deliver to be the origin of the problem.
I think it is the same problem than here http://dovecot.org/pipermail/dovecot/2006-July/014786.html , my "From" headers are badly duplicated.
Could this be fixed before the dovecot 1.0 release ?

You should find out what exactly gets changed. Find the mail from "Sent messages" mailbox and compare it to the one in the destination mailbox. What is different? Or is it already broken in the "Sent messages" too?

That bug was already fixed, so it can't be the same.

What do you mean by this?

Thanks you for your answer.
Here is as attachement a diff of two maildir files : the one in the sent folder, and the one received in an external domain. I believe a big part of the problem is located in these lines of the attached file.

Do you think dovecot is altering the mail, or the problem is located inside our smtp server ? (this problem happen with any remote domain.)

I didn't really understand where you're forwarding the mail to. Is Dovecot also running there?

The extra '>' is added if the other server stores mails in mbox format and the mail isn't saved with Dovecot LDA. Dovecot currently doesn't remove the '>' from ">From " lines. Perhaps in future it should.
But are you even running Dovecot in the remote server? Is this a Dovecot problem at all?

I was forwarding a mail comming from a user of the same domain (we are running dovecot/maildir), to another domain which is running cyrus-imap on mailbox.

Thanks for your answer. Samuel HAMEAU

So you have a correct mail in Dovecot system, but after sending it via SMTP to Cyrus running server it's broken in there? And if you look at it in Dovecot's "Sent messages" mailbox, it's still correct in there? If so, it can't be a Dovecot problem.

It seems we have a transport problem, and dovecot is not related to this. Thanks you for your help, and for the 1.0 release !!!

Hello Samuel,
I don't like -e diff's so I might be wrong:
The "From " (no colon) line appears to be located in line #25 of the original message, that's either:
a) not correct, because the line must be the first line of the message, or b) is part of the mail body. In which case, Timo already answered you.
If you find another problem of this, please post all lines of both the original and the forwarded mail up to the first empty line.
