Hi!

It looks like postfix is ignoring aliases.db in some cases. Assume settings
in postfix.rc.config:

POSTFIX_CREATECF="yes"
POSTFIX_RELAYHOST="snoopy.nic.home.net"
POSTFIX_NULLCLIENT="no"
POSTFIX_MASQUERADE_DOMAIN=""
POSTFIX_LOCALDOMAINS=""

and aliases like:

root:           \root, tschweikle@xxxxxx

# Basic system aliases that MUST be present.
mailer-daemon:  root
postmaster:     mailer-daemon

# General redirections for pseudo accounts in /etc/passwd.
daemon:         root
lp:             root
news:           root
uucp:           root
games:          root
man:            root
at:             root
postgres:       root
[...]

a mail to root should be delivered localy _and_ forwarded to
tschweikle@xxxxxxx In the logs you see:

xcnlm03s:/etc # mail -s Test root
Test
.

xcnlm03s:/etc # tail /var/log/mail

Mail will only be delivered to root!

Setting

POSTFIX_LOCALDOMAINS=""

to "localhost mm.home.net" makes postfix respect aliases.db:

xcnlm03s:/etc # mail -s test root
Test
.
EOT
xcnlm03s:/etc # tail -n 5 /var/log/mail
