Can you try with valgrind? It will slow down the logins a bit though.

The following hack seems to eliminate the symptom, however I'd strongly recommend to take a deeper look at the issue. I suspect that a higher level fix would be more appropriate. --- dovecot-2.0.rc6.ori...

Hi Timo, are the latest 'Auth-Changes' supposed to be complete? They break 'alias at domain.tld' logins for me. Regards Thomas

Dear list, since the distri upgrade to glibc 2.28, i can't build working dovecot binary's. Older with glibc 2.27 are working. The distri is LFS based. MariaDB 10.2.18 and 10.3.11 makes no difference.
