saslauthd imap and postfix?

[chrisu]

hi there,

i have since a few month open-xchange running on my debianbox.
one of my friends where asking me to setup the smtp-authentication.

i´ve tried it out and have setup the saslauth path to
/var/spool/postfix/var/run/saslauth

it works for postfix but not any more with imap/pop.. so how can i setup
it that both is running via pam-saslauthd?

thanks for any help.

greetings

chris
