Strange mail.log messages

Anyone ever seen this before, it is causing mail.log to fill /var vary quickly.

Re: Strange mail.log messages

Hello,


Probably sendmail connections in SYN_RCVD state (waiting
on a SYN_ACK)..... Eventually, they timeout.

You should check if all the SYN_RCVD are from outside the network (remote connections) going through a firewall/router or something else.

I know of one case where it resolved temporarly by restarting the daemon.
