I'm getting a huge number of "NOQUEUE: no connection" messages on my sendmail log.
Corresponding to those there are lots of processes that look like this: [root@mail log]# ps ax | grep sendmail 486 ? S 0:21 sendmail: accepting connections on port 25 32559 ? S 0:00 sendmail: startup with f244.law12.hotmail.com When I did this particular ps, there were 14 of these processes, each corresponding to a NOQUEUE log thus: sendmail[32559]: NOQUEUE: Null connection from f244.law12.hotmail.com [64.4.19.244] Should I be worried? The server doesn't appear to be open relay. I've tested it using http://www.abuse.net/relay.html The processes seem to persist for some time. I can't find any sign of legitimate mail from these hosts. They are mostly hotmail or sydhosmtp01.westfield.com.au [root@mail log]# grep sydhosmtp01.westfield.com.au maillog | wc -l 322 [root@mail log]# David. -- SLUG - Sydney Linux User Group Mailing List - http://slug.org.au/ More Info: http://lists.slug.org.au/listinfo/slug
