I was trying to configure the postfix to send mail only.
Mar 21 06:36:50 localhost postfix/postfix-script[8747]: starting the Postfix mail system
Mar 21 06:36:50 localhost postfix/master[8748]: daemon started -- version 2.6.6, configuration /etc/postfix
Mar 21 07:14:21 localhost postfix/pickup[8750]: 7443121B13: uid=0 from=
Mar 21 07:14:21 localhost postfix/cleanup[8852]: 7443121B13: message-id=<20140321071421.7443121B13@myhostname.com>
Mar 21 07:14:21 localhost postfix/qmgr[8751]: 7443121B13: from=, size=513, nrcpt=1 (queue active)
# mailq
-Queue ID- --Size-- ----Arrival Time---- -Sender/Recipient-------
7443121B13* 513 Fri Mar 21 07:14:21 root@myhostname.com
(connect to mta7.am0.yahoodns.net[98.138.112.38]:25: Connection timed out)
myemailaddress@yahoo.com
# postconf -d mydestination
mydestination = $myhostname, localhost.$mydomain, localhost
# postconf -d inet_interfaces
inet_interfaces = all
Anyone has a clue?
