Using the latest versions of the above packages.

postfix is setup and works using mysql. SMTPD works using authdaemond for authentication so that bit is fine.

My postfix master.cf has:

maildrop unix - n n - - pipe
flags=DRhu user=vmail argv=/usr/bin/maildrop -d {$recipient}

enabled.

Package courier-maildrop is installed.

Firstly using postfix internal delivery (virtual_transport=virtual) it works perfectly and mail goes to the correct user.
Also using maildrop -V 7 -d me@test.testdomain.co.uk results in correct recognition and filtering to the virtual users mail box so i assume the maildroprc file is fine.

The problem is when i try to get postfix to deliver via maildrop by setting virtual_transport = maildrop.

Suddenly now i get errors.

In /var/log/mail/log i have
When i try to send a mail to that user.

Any idea what's wrong or broken here? Im a bit stuck given postfix works with its internal delivery, maildrop works with authtest and direct commend line but invalid user when combined with postfix to receive.

Bad form to reply to own post but a little more information now.

This problem seems to be entirely how postfix is calling Maildrop.

Maildrop command line runs fine and puts mails in the proper directory.

However with the following in my postfix/master.cf:

it tries to put all the mail in /home/vmail/.Mairdir

Somehow postfix isnt sending or maildrop isn't receiving the correct path for the users mail directory.

Any ideas at all why this is?
