Issue:
warning: SASL authentication failure: cannot connect to saslauthd server: Too many levels of symbolic links

Fix:
rm -r /var/run/saslauthd/
mkdir -p /var/spool/postfix/var/run/saslauthd
ln -s /var/spool/postfix/var/run/saslauthd /var/run
chgrp sasl /var/spool/postfix/var/run/saslauthd

Problem:
An apt-get install is not replacing deleted config files…

Example:
Setting up dovecot-common (1:1.2.12-1ubuntu8.3) …
Not replacing deleted config file /etc/dovecot/dovecot.conf
Not replacing deleted config file /etc/dovecot/dovecot-ldap.conf
Not replacing deleted config file /etc/dovecot/dovecot-sql.conf
grep: /etc/dovecot/dovecot.conf: No such file or directory
grep: /etc/dovecot/dovecot.conf: No such file or directory

Solution:

apt-get --purge autoremove package


Install Postfix:
yum install postfix (RedHat)
apt-get install postfix (Debian)

Add Domains to Accept Mail For:
vi /etc/postfix/main.cf
set
mydestination = localhost.localdomain, localhost, domain.com, host

Tell Postfix to use Maildir instead of mbox format:
postconf -e "home_mailbox = Maildir/"
postconf -e "mailbox_command ="

Set MAIL variable in /etc/profile:
export MAIL=$HOME/Maildir

Restart Postfix:
service postfix restart

Mail local user and confirm mail is delivered.

Install Dovecot:
apt-get install dovecot-common dovecot-imapd dovecot-pop3d
