sendmail lost input channel


I've been seeing a lot of "lost input channel" at /var/log/maillog of sendmail-8.12v. Any ideas what's causing this?

Second question:

When i run the command "mailq" i see a lot of MAILER-DAEMON connection time out with my.love.pochta.ru, can i trace down from what computer is this coming from?

Hope you give me some help. thanks!
