Re: postfix and SASL

SASL gives you the possibility to authenticate users.
Email from mynetworks can send EMail. If you have people who don't
connect to your mailserver from mynetworks (e.g. people with a notebook
from a hotel, or people working at home) can not send mail through your
mail server. Here comes in SASL that lets you authenticate these users
comming from other networks allowing them to send mail.

In addition if you have a IMAP server running your users can use the
same password for their IMAP/POP account and for sending out mail.
