Jul 9 06:26:47 XXXXX sendmail[6025]: m687K2op001151: to=<XXXX@gmail.com>, delay=16:06:45, xdelay=00:14:03, mailer=esmtp, pri=1561040, relay=gsmtp183.google.com. [64.233.183.27], dsn=4.0.0, stat=Deferred: Connection timed out with gsmtp183.google.com.

I think problem come from firewall in CentOS(Both Firewall and selinux are disable).
Because I try "telnet gsmtp183.google.com 25" I can't connect.
while I try in Windows XP that respond "220 mx.google.com ESMTP f4si49893210nfh.27".

(Both Windows XP and CentOS are same network)

Please advice me for solve this problem.
Thank you.

How or why do you think it is the firewall?
