[Dovecot] Popping without home directories

Hello there

I tend to e-mail user accounts to my servers with /sbin/nologin and /dev/null as their shell and home directories respectively.

I have discovered that Dovcot does not like it when a user does not have a home directory. Obviosly the user POP3 and not IMAP! :P Is there a work around for this? I have a suspicion it is one of the chroot option, but I do not know the meaning chroot.

Thanks

Andre
