Hey guys, I'm seeing in my logs 2 things causing me some concern, I don't need to go in to all my settings, just looking to see if anything stands out from the message and common causes:
Jun 3 14:22:41 PHX1-1831 postfix/smtpd[2092]: warning: hostname cleers.dustypex.com does not resolve to address xx.xx.xx.xx: Temporary failure in name resolution Jun 3 14:22:41 PHX1-1831 postfix/smtpd[2092]: connect from unknown[xx.xx.xx.xx] Jun 3 14:22:41 PHX1-1831 postfix/smtpd[2092]: improper command pipelining after EHLO from unknown[xx.xx.xx.xx]: HELO hostname.domain.net.net\r\n First is probably someone trying to relay to my server, the cleers.dustypex.com hostname is not one of mine, but the ip I X'd out is mine, so my guess is they try to connect on that ip and send mail, and postfix is stopping it? I've gotten maybe 1000 of them in the last 2-3 days. The 2nd is the last log line, I saw a bunch of those today, none before today, improper command pipelining, I removed the ip and host/domain but they are mine, my thought was maybe it was sending EHLO and then a HELO after it? or maybe just the wrong command? If possible to just give me a general direction it would be easier for me to debug it myself than posting lots of logs, and explaining my config, I'm out of ideas so any past experience with that error message would probably help a lot. Thanks! Paul
