Hi, I'm trying to set up dovecot 1.1.2 and postfix 2.5.4 on freebsd 7.0. I'm getting permissions problems on auth-master and I'm not sure of the correct settings to use.

In postfix's main.cf I have mailbox_command=/usr/local/libexec/dovecot/deliver -d $USER

In dovecot.conf I have: socket listen { master { path = /var/run/dovecot/auth-master mode = 0660 user = dovecot group = postfix } ...

leave the master as it was and add a client for postfix:

 client {
   path = /var/spool/postfix/private/dovecot
   mode = 0660
   user = postfix
   group = postfix
 }

then configure your postfix to use private/dovecot

# ls -l /var/run/dovecot/auth-master srw-rw---- 1 dovecot postfix 0 Sep 18 18:26 /var/run/dovecot/auth-master=

In maillog I'm getting: deliver(sumbuddy): Can't connect to auth server at /var/run/dovecot//auth-master: Permission denied (I'm not sure where it's getting the "//" in the path either ...)

Also I'm confused about whether I need the postfix options: maildrop_destination_recipient_limit=1 dovecot_destination_concurrency_limit=1

Assuling "dovecot" is the name of the corresponsing transport in master.cf, use dovecot_destination_recipient_limit = 1

or even whether these are current options in my version of postfix (they don't appear in main.cf.default)

they won't even appear in postconf output. Unlike most postfix parameters, these have a "free" prefix. if you have a transport named FOOBAR in master.cf, you can use FOOBAR_destination_recipient_limit in main.cf.

Does deliver require such limits on concurrency or # of recipients?

when delivering mail to a mailbox with a command, you need to pass one recipient at a time. This is because if delivery fails for one recipient and succeeds for another, the command has no way to tell postfix about this (you need LMTP for such a functionality). so the choice is between: saying "OK" and losing mail for one recipient, or saying "not ok" and delivering multiple copies to the other.
