Hi, i installed smtp-auth for postfix via saslauthd. it seems to work properly, unfortunately i can only check on a webclient now (squirrelmail). i indicated squirrel to do smtp authentication. what i get is the following error: May 7 10:25:01 link saslauthd[17730]: do_auth : auth failure: [user=rogerg] [service=smtp] [realm=] [mech=pam] [reason=PAM auth error] somehow, i think, my password is not delivered...but not sure.. do you have any idea? ah, yeah i do authenticate via mech=PAM Thanks for any help!
