Check greet_pause function
in [Sendmail]
|
From: Rick Knight on 7 Oct 2009 14:57 I have just enabled the greet_pause feature. I'm wondering if there is a way to check it's function? I don't see anything in the message headers. Thanks, Rick

If you see multi-second (however long you set it for) pause before the "220" banner, it's probably working. Type "quit", telnet in again, and type "helo example.org" (or some other domain) before the "220" banner. If you aren't telneting in from a host exempt from greet-pause, you should get a failure line Oct 7 00:28:14 <2.6> <foo> sm-mta[93463]: n975SEQT093463: rejecting commands from [bar.example.com] [bar.example.com] 2759 due to pre-greeting traffic in your maillog, and a nastygram in your telnet session from sendmail. $ telnet foo 25 Trying 192.149.244.25...
