Hii,
I had installed postfix in Ubuntu 16.04 and it was working seamlessly. Some
time back I upgraded it to Ubuntu 18.04 and suddenly emails stop coming to
my inbox. It gave me this error:
postfix/postdrop[27466]: warning: mail_queue_enter: create file
maildrop/675261.27466: Permission denied
Somoene messed up file permissions, or someone decided
to break setgid programs.
It might be unrelated but in the dovecot debian package the
systemd service file includes (included?) the option
"NoNewPrivileges=false", which causes (caused..) many problems.
In my case, forwarding mails (via a sieve filter), didn't work because
dovecot/sieve could not use postdrop.
I don't know whether Ubuntu makes use of this option in either dovecot,
postfix, or both, but it may be worth checking..
Cheers,
