Hi,

With latest 2.3 -git (and 2.3.0 release), I'm running into this error with Thunderbird:

"An error occurred while sending mail. The mail server responded: 5.5.4 Unsupported mail BODY type. Please verify that your email address is correct in your account settings and try again."

This is fatal and means Thunderbird cannot use the submission service

• fortunately I can revert back to a native Postfix service which works.

Here's a tcpdump of the conversation:

thunderstorm /etc/dovecot/conf.d # tcpdump -A port 587

dropped privs to tcpdump tcpdump: verbose output suppressed, use -v or -vv for full protocol decode listening on eth0, link-type EN10MB (Ethernet), capture size 262144 bytes

I cannot reproduce this behavior so far.

The odd thing is, I can 100% of the time reproduce this with the client, but 100% not reproduce it if I put the commands in by hand, at least up to the MAIL FROM: part of the conversation.

Here's the TB log:

(ngrep -Wbyline produces more readable output)

Thanks. ngrep seems to hate IPv6 though, but after a bit of forcing IPv4 it started working (the output was the same as the tcpdump).

I will continue experimenting a bit. I still have to actually try this with Thunderbird. Any other configuration I should know about (dovecot -n)? I think that'd help. I'm using Thunderbird on Windows.

This thread might be of interest:

http://forums.mozillazine.org/viewtopic.php?f=39&t=2849171 https://bugzilla.mozilla.org/show_bug.cgi?id=1032302

It all seems to suggest that this could be a client side specific bit of quirkiness that dovecot submission is not handling.

Config is up here:

Thanks, Reuben
