dovecot - Jun 2007 - Domain part / auth_username_format

Hey folks,

I want to authenticate a pop3 user without a domain part and then use 
the domain part to specify a Maildir subfolder to grab messages from.

So, this was my attempt:
  # use the domain part to access a subfolder
  mail_location = maildir:/mail/%n/Maildir/%d
  # strip of the domain part for authentication purposes
  auth_username_format = %n

login: testuser at .INBOX.SubFolder

Authentication of testuser works great, but mail_debug shows me that the 
domain-part (%d) is empty when expanding mail_location.

Any bright ideas?

Rob :)

Do you mean that you want to have user at domain1.org and user at domain2.org
have the same password but different maildirs? What passdb and userdb
are you using? I don't think there's a way to do this with auth_*
settings. With SQL it would be easy.

Yes. Basically using the domain part as a variable :)

Currently I'm using PAM, but I could probably hack up a checkpassword
script or some sql auth. auth_username_format is very close except the %d
disappears when it comes to evaluate mail_location!

Thanks,
