No. do not the same user for different services: - keep the 'postfix' account for the postfix "server" - use amavis or vscan or whatever for amavisd-new - create a mailbox user and configure postfix to deliver mail as this user - courier-imap is generally run as root. if this is not needed, you can run it as the "mailbox" user > Is it easy to adjust configuration for this new user? > > Also, I think this is not causing my duplicate email, right? > as Viktor said, this makes troubleshooting harder. in this particular case, we have a message submitted by user 207, but we have no idea which service or program submitted the message.
