I have migrated from Centos 6.X to this new server on Centos 7.9 and the server gave me pure hell in all departments. I have sorted them out except for the emails.
I have an odd problem: Emails appear to be delivered as I find no error - but they don’t land in the Maildir (inbox). In short the emails just vanish into thin air.
This server has no quota set. If the emails are dropped silently where should I look ?
I would appreciate any pointers. TIA
How did you migrate, via a VM backup and restore as I think that would be the safest bet.
Logs are you best help. Things should not just disappear.
Also why would you go from a very old OS to a old OS.
