http://bugzilla.opensuse.org/show_bug.cgi?id=1084014 Bug ID: 1084014 Summary: SMTPUTF8 mail rejects Classification: openSUSE Product: openSUSE Distribution Version: Leap 42.3 Hardware: Other OS: openSUSE 42.3 Status: NEW Severity: Major Priority: P5 - None Component: Network Assignee: varkoly@suse.com Reporter: suse-beta@cboltz.de QA Contact: qa-bugs@suse.de CC: chris@computersalat.de Found By: Beta-Customer Blocker: --- With Leap 42.3, Postfix was upgraded from 2.11.8 to 3.2.0. Since this upgrade, I see mail rejects caused by SMTPUTF8, for example: - dovecot lmtp (mail address and hostnames anonymized) Mar 5 10:13:14 server postfix/lmtp[2703]: 3636F1D273DC: to=<user@example.com>, relay=mail.example.com[private/dovecot-lmtp], delay=0.03, delays=0.03/0/0/0, dsn=5.6.7, status=bounced (SMTPUTF8 is required, but was not offered by host mail.example.com[private/dovecot-lmtp]) - amavis (mail address anonymized starting at "user=", hostnames anonymized) Feb 15 12:38:28 server amavis[3273]: (03273-17) ESMTP: 501 5.5.4 Syntax error in MAIL FROM parameters; smtp_resp: MAIL FROM:<bounce+28f75a.232d6-user=example.com@mail.example2.com> BODY=8BITMIME SMTPUTF8\r\n So both amavis and dovecot lmtp do not understand SMTPUTF8 and reject the mails. "Luckily" this only affects a few mails per day, but that also means the problem will probably stay unnoticed in most cases. As a workaround, I set smtputf8_enable = no I don't have a 42.2 system anymore to check what the default was there, but my guess is that it was set to 'no' there. For 42.3, I'd recommend to release a postfix update that changes the default for smtputf8_enable to 'no'. For Tumbleweed and Leap 15, please make sure that both amavis and dovecot lmtp understand SMTPUTF8. -- You are receiving this mail because: You are on the CC list for the bug.
