hi all, for the last weeks I was detecting a problem in my sendmail MTA. This is some lines from my sendmail.log Jun 26 16:28:27 smtp sendmail[1545]: h5QFSPiQ001545: from=<>, size=0, class=0, nrcpts=0, proto=ESMTP, daemon=MSA, relay=omr-r09.mx.aol.com [152.163.225.154] Jun 26 16:28:51 smtp sendmail[1550]: h5QFSgiQ001550: from=<>, size=4529, class=0, nrcpts=0, proto=ESMTP, daemon=MSA, relay=gandalf.warpdrive.net [24.56.130.20] Jun 26 16:32:38 smtp sendmail[1607]: h5QFWXiQ001607: from=<>, size=0, class=0, nrcpts=0, proto=SMTP, daemon=MSA, relay=mx1.thebiz.net [216.238.0.21] Jun 26 16:34:34 smtp sendmail[1630]: h5QFYWiQ001630: from=<>, size=0, class=0, nrcpts=0, proto=ESMTP, daemon=MSA, relay=omr-r09.mx.aol.com [152.163.225.154] Jun 26 16:34:55 smtp sendmail[1633]: h5QFYriQ001633: from=<>, size=5120, class=0, nrcpts=0, proto=ESMTP, daemon=MSA, relay=smtp03.infoave.net [165.166.0.28] Jun 26 16:36:20 smtp sendmail[1644]: h5QFaHiQ001644: from=<>, size=4693, class=0, nrcpts=0, proto=ESMTP, daemon=MSA, relay=e35.co.us.ibm.com [32.97.110.133] Jun 26 16:38:15 smtp sendmail[1653]: h5QFcDiQ001653: from=<>, size=3302, class=0, nrcpts=0, proto=ESMTP, daemon=MSA, relay=blackbox.inta.net [194.70.70.70] Jun 26 16:42:27 smtp sendmail[1713]: h5QFgPiQ001713: from=<>, size=3453, class=0, nrcpts=0, proto=ESMTP, daemon=MSA, relay=fep21.swip.net [130.244.199.149] I'm using SuSE 8.0 version with sendmail 8.12.3-75, and I implemented some modifications in linux.mc in order to activate dnsbl, and so far is ok. I made some open relay test and I'm sure that every thing is well done.... Does any one know how to solve this problem?
