In postfix master.cf, there are entries like this (for dovecot):

dovecot unix - n n - - pipe flags=DRhu user=vmail:vmail argv=/usr/lib/dovecot/deliver -f ${sender} -d ${user}@${nexthop} -n -m ${extension}

As far as i understand it, variables like ${sender}, ${user}, ${nexthop}, ${extension} are provided by postfix, but I was not able to find documentation of a list of all possible parameters. I need to know if there are more variables than these... As I have problems setting up my system as intended. I am looking for a variable that represents the mapping for an email to a virtual mailbox-username...

If someone knows where I can find such a list, I would be very thankfull!

Thanks very much!

As you see, the command name is pipe. This is a postfix built-in way to deliver mails to an external program, in this case dovecot.

The accepted parameters as well as the available variables are documented in its man page.

  • Hello Holger, Thanks ver much!!! I was not aware of that pipe is the command. I thought this is solely related to master (and in the master man page I had not found anything). Thanks very much, your answer made verything clear and was what i was looking for. thanks! – Markus Jul 14 '11 at 13:41
