С новым dovecot ntlm_auth (ожидаемо) один раз уже упал.
А можно ли описать примерный сценарий, чтоб попробовать воспроизвести?
Сценарий довольно обычный. Есть домен на самбе (все еще в режиме NT4) с
пользователями в openLDAP. Dovecot берет пользователей из доменного
LDAP, авторизуя их самостоятельно с помощью LDAP bind по алгоритмам
PLAIN и LOGIN и используя ntlm_auth для авторизации их же по NTLM. На
той же машине установлен winbind, введенный в домен. Вся почтовая
система работает под одним пользователем vmail. Используется sieve.
Вроде никаких особенностей...
