we are currently using vm-pop3d to implement virtual domains. But due to some locking problem in vm-pop3d, we want to test the possibility to change to dovecot. Currently, in vm-pop3d, the passwd file is located in /etc/virtual/domain1.com/passwd /etc/virtual/domain2.com/passwd

passdb passwd-file { args = /etc/virtual/%d/passwd }

This requires Dovecot 1.0.alpha2 or later.

and the passwd format is: user: md5 encrpted password

In MD5crypt format? ie. $1$something? Then it should work directly.

and the email is store in /var/spool/virtual/domain1.com/user /var/spool/virtual/domain2.com/user

As mboxes? For IMAP you'll need also some directory where non-INBOXes are stored, and with POP3 Dovecot also wants a directory where it can store index files.

If you don't want either, you could do something like:

default_mail_env = mbox:/tmp:INBOX=/var/spool/virtual/%d/%u:INDEX=MEMORY

Thank you. Timo. I have installed Dovecot 1.0 alpha3 and tested. It is a mbox POP3 only server. The relevent part of dovecot.conf I have changed:

default_mail_env = mbox:/tmp:INBOX:/var/spool/virutal/%d/%u:INDEX=MEMORY

passdb passwd-file { # Path for passwd-file args = /etc/virtual/%d/passwd }

userdb static { args = uid=503 gid=503 mail=mbox:/var/spool/virtual/%d/%n }

I can login with user@domain1.com but there is error in logfile: Sep 27 13:15:16 ns2 dovecot: pop3(user@domain1.com): mbox: Can't create root IMAP folder /mail: Permission denied Sep 27 13:15:16 ns2 dovecot: pop3(user@domain1.com): Failed to create storage with data: mbox:/var/spool/virtual/domain1.com/user Sep 27 13:15:16 ns2 dovecot: pop3-login: Login: user=<user@domain1.com>, method=PLAIN, rip=127.0.0.1, lip=127.0.0.1, secured Sep 27 13:15:16 ns2 dovecot: child 19147 (pop3) returned error 89

I then created a /mail directory with file mode 777, then it is OK.

Why I need a IMAP folder in a POP3 only server and can I change that folder to /tmp directory.
