Would like to install sendmail with smtp auth on new solaris-9 box which is to replace an older solaris box .the machine is an all-in-one mailserver (incoming and outgoing smtp, not currently using auth, using old version of sendmail, also pop, imap and some shell-based email clients (pine))
I want to know-
do I understand correctly that the only auth method available is plain if I want to use pam/unix (files) for authentication?
otherwise, I have to create a separate sasl database for sendmail to talk to??? (or else use ldap?)
could someone explain to me why this is? is it the type of encryption used in /etc/shadow (crypt) passwords?
supposing I put the smtp auth on a linux box instead, and split that functionality off of this machine. and used this machine just for mailbox storage (imap, pop,) and incoming smtp, and relaying restricted to the local net.
would there be any way to sync passwords between the two machines so that pop and imap passwords matched smtp passwords? assuming people generally need to be able to change them on the solaris machine (shell users)
