100%, Works great for me.
Took me 3 minutes to set up incl. building certs
Redhat default config is pretty self explaining. :-)
# make -C /usr/share/ssl/certs sendmail.pem
and comment out the corresponding 4 lines in sendmail.mc
If you also want to cover imap and spamassassin in your document, this
is what I did.
1. Install dovecot, no configuration necessary.
2. Install spammassassin
# yum install spamassassin
# cd /etc
# cp mail/spamassassin/spamassassin-spamc.rc procmailrc
# echo "allow_user_rules 1." >> /etc/mail/spamassassin/local.cf
# chkconfig spamassassin on
# service spamassassin start
5. Install and configure fetchmail
#cat ~./fetchmailrc
poll some.server.com
proto pop3
user "user at server.com"
pass "pass"
is localuser (your Username :-))
fetchall
ssl
poll another.server.com
...
You are ready to go:
fetchmail -> sendmail -> procmail -> spamassassin -> dovecot :-)
Thanks for your tips.
