dovecot-submission SMTP send error with Thunderbird (BODY=8BITMIME)
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 14:12:19.975982 IP6 2001:44b8:31d4:1311:45ec:e191:8093:3e9d.61175 > inside-mail.reub.net.submission: Flags [S], seq 572328223, win 64800, options [mss 1440,nop,wscale 8,nop,nop,sackOK], length 0 `._.. .? .D.1...E.....>. .D.1..........#...K". ........ .w.............. 14:12:19.976022 IP6 inside-mail.reub.net.submission > 2001:44b8:31d4:1311:45ec:e191:8093:3e9d.61175: Flags [S.], seq 3954361671, ack 572328224, win 28800, options [mss 1440,nop,nop,sackOK,nop,wscale 7], length 0 `.c|. .@ .D.1..........# .D.1...E.....>..K.....G". ..p.:4.............. 14:12:19.976158 IP6 2001:44b8:31d4:1311:45ec:e191:8093:3e9d.61175 > inside-mail.reub.net.submission: Flags [.], ack 1, win 8235, length 0 `._....? .D.1...E.....>. .D.1..........#...K". ...HP. +. .. 14:12:19.983409 IP6 inside-mail.reub.net.submission > 2001:44b8:31d4:1311:45ec:e191:8093:3e9d.61175: Flags [P.], seq 1:43, ack 1, win 225, length 42 `.c|.>.@ .D.1..........# .D.1...E.....>..K.....H".

Use the normal Dovecot rawlog facilities to capture protocol interaction with the client instead. Well, now we do know for sure that Dovecot is responsible for the error, since the interaction with the relay server shows no issues. I will continue experimenting a bit. I still have to actually try this with Thunderbird. Any other configuration I should know about (`dovecot -n`)? Regards, Stephan.

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.
