Hello, @shadowlmd I'm trying to reproduce this bug.
I tested this version of postfix with a simple configuration on different clouds, but I don't have access to Oracle cloud at the moment, so this may be indeed Oracle-specific. I see you have postfix version 3.6.4-1ubuntu1.3, and you mentioned automatically installed updates. Do you happen to know if the bug started when a postfix upgrade happened? Moreover, could you please help us finding a reproducer? Are there steps, from a fresh Ubuntu install, to see this bug (even if it is only in Oracle cloud)? ** Changed in: postfix (Ubuntu) Status: New => Incomplete -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/2100610 Title: Postfix: start operation timed out after system reboot To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/postfix/+bug/2100610/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
