One day, I'll use the LDAP. But infrastructure I got is quite neglected
and some older admins is hard to convince to innovate. Just, aaaaah :)
I read whole documentation related to userdb a and passdb. Easy to
understand with relation to IMAP or POP3 access. But what I didn't
understand is relation to LMTP. Which one is used and when for
successful delivery.
I'll try to move those settings as global.
Thank you, Milo
