Hi,

I'm attempting to install Courier-mta, using Ldap for user details, and integrate spamassassin / mailscanner for spam filtering.

I've worked my way through courier-authlib, and using authtest can retrieve user credentials from Ldap, and am feeling rather happy with myself for having done that on my own largely thanks to the wonderful documentation.

I've successfully worked my way through building the courier package, and I've reached the section in the install doc which talks about PAM configuration. This is a little confusing as it talks about using PAM as an authentication source, and I thought I had dealt with that with courier-authlib.

Would I be correct in thinking that PAM authentication will be used for allowing somone connect to the services externally, ie. as a replacement for dracd / some other kind of pop-before-smtp scheme, where the PAM system knows based on whatever criteria who is allowed to get in and will block all others?

Thanks,

Aine.
