Could anyone explain to me the "Code Listing 4.2: Starting sasl" of http://www.gentoo.org/doc/en/virt-mail-howto.xml or more precisely the following lines (not explained in this tutorial):
Code:
# nano -w /etc/conf.d/saslauthd
SASLAUTHD_OPTS="${SASLAUTH_MECH} -a rimap -r"
SASLAUTHD_OPTS="${SASLAUTHD_OPTS} -O localhost"

By default there is:
Code:
SASLAUTHD_OPTS="${SASLAUTHD_OPTS} -a pam"

What is practical advantage of redirecting requests to local IMAP server instead of just using the pam?
Best regards,
Marek

I would assume the advantage would be in a situation where you use say, cyrus-imapd, and your users are not local passwd users, but rather are maintained by imap itself

just a guess, albeit a half-educated one
