I'm still weighing my options and may go with the PPA dovecot. I'm not able to evaluate the regression potential for the fix. For reference, here are my findings:
Bug may cause direct loss of user data. If user has active sieve-script with both vacation extension and keep action (implicit or explicit), the keep action part will lead LMTP delivery to crash: Aug 17 13:41:38 XXXX dovecot: lmtp(XXXXX): Fatal: master: service(lmtp): child 10177 killed with signal 11 (core dumped) Local (keep) copy will not be delivered. If sieve script has redirect- action, that'll work. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1710808 Title: dovecot lmtp crash with sieve To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/dovecot/+bug/1710808/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
