I've just set up a new account with new domain on my postifx server, but when I try to log in receive this error:
ERROR: Connection dropped by IMAP server.
I checked if /home/vmail and subdirectories have right permissions set, but everything is OK. /home/vmail directory owner is vmail (in vmail group) and chmod is 700.
I think it's problem of vmail directory because postfix application hasn't created any directory for my new domain and subdirectory for my account on this domain.
Everything in MySQL tables is right.
