# when ipv6 is disabled on the loopback adapter and a mail message
# delivery attempt fails because the recipient doesn't exist, postfix
# returns reason "Host or domain name not found. Name service error

# reason "User doesn't exist." The sysadmin's intent is probably that
# ipv6 is not desired at all, so disable ipv6.

# Tweak some queue settings:
# * Inform users when their e-mail delivery is delayed more than 3 hours (default is not to warn).
# * Stop trying to send an undeliverable e-mail after 2 days (instead of 5), and for bounce messages just try for 1 day.
