It looks like one of your users (the "ctladdr=" one) is trying to email [EMAIL PROTECTED] company.com doesn't appear to be online right now, which is why the connection is timing out.
For the SYN_SENT when doing a netstat, it's likely that your mail server is trying to connect to those mail servers, which are either not online or have some firewall rules blocking you - nothing to worry about. (sending a TCP packet with the SYN flag set is the first step to making a connection, if those servers were online and responding they would reply with a packet with SYN + ACK set, since your server can't get to them the connection is stuck in the SYN_SENT state until it times out) -Greg > hi guys in my maillog I am receiving many strange message on sendmail like > that: > May 10 18:52:50 xserver sendmail[4444]: g4AIRfa02119: > to=<[EMAIL PROTECTED]>, ctladdr=<one of my user mail> (638/45), > delay=03:25:09, xdelay=00:00:00, mailer=esmtp, pri=607606, > relay=company.com., dsn=4.0.0, stat=Deferred: Connection timed out with > company.com. > > and the other strange thing is that when i try to check the > conections(netstat -at) there are one strange like that: > tcp 0 1 myserver:35169 mywebos.com:smtp SYN_SENT > when I use netstat -atn looks like that: > tcp 0 1 myserver:35169 208.49.229.140:25 SYN_SENT -- ------SupplyEdge------- Greg Hunt 800-733-3380 x 107 [EMAIL PROTECTED] -- To UNSUBSCRIBE, email to [EMAIL PROTECTED] with a subject of "unsubscribe".
