[IMail Forum] MX connect fail

[rs]

Hi,   i have seen this problem before, but did not catch the solution. May be someone can remember. Problem shows as following:   Imail server is a nt4-box, sp5 installed. 2 NICs, one for internet, the other for intranet. server does DNS with upstream DNS by ISP (194.25.0.125).   IP on internet is 194.25.187.226 (imail.bechtle-online.de, as well as ez-online.de)   imail is hosting 4 domains: bechtle-online.de, ez-online.de the other two are in progress of registering.   all incoming messages will be processed correct. Whenever I try to send a message, smtp logs the following:   08:18 19:02 SMTPD(013E01FA) server starting on port 25 of imail.bechtle-online.de Spooldir: D:\IMAIL\spool ConfigDir: D:\IMAIL\cfg UsersDir: D:\IMAIL\users SendPgrm: D:\IMAIL\SMTP32.exe Accepting mail for remote hosts Relaying mail for local hosts Denying remote mail to local lists Denying remote view of lists [x] official name imail.bechtle-online.de [x] address 127.0.0.1 [x] address 194.25.187.226 [x] address x.x.x.x (internal address) [x] address x.x.x.x (internal address) [x] address x.x.x.x (internal address) [x] address x.x.x.x (internal address) 08:18 19:02 SMTP-(00000143) MX connect fail "212.122.129.2" 08:18 19:02 SMTP-(00000143) requeuing D:\IMAIL\spool\Qd6be274.SMP R0 T9 08:18 19:02 SMTP-(00000143) finished D:\IMAIL\spool\Qd6be274.SMP status=3 08:18 19:03 SMTPD(0063027C) [194.25.187.226] connect 194.25.187.226 port 3098 220 X1 NT-ESMTP Server imail.bechtle-online.de (IMail 5.05 1-1) QUIT 221 Goodbye 08:18 19:04 SMTPD(006A027C) [194.25.187.226] connect 194.25.187.226 port 3109 220 X1 NT-ESMTP Server imail.bechtle-online.de (IMail 5.05 2-1) QUIT 221 Goodbye 08:18 19:05 SMTPD(018F0216) [194.25.187.226] connect 194.25.187.226 port 3120 220 X1 NT-ESMTP Server imail.bechtle-online.de (IMail 5.05 3-1) QUIT 221 Goodbye 08:18 19:06 SMTPD(004B0222) [194.25.187.226] connect 194.25.187.226 port 3130 220 X1 NT-ESMTP Server imail.bechtle-online.de (IMail 5.05 4-1) QUIT 221 Goodbye 08:18 19:07 SMTPD(01550224) [194.25.187.226] connect 194.25.187.226 port 3140 220 X1 NT-ESMTP Server imail.bechtle-online.de (IMail 5.05 5-1) QUIT 221 Goodbye 08:18 19:08 SMTPD(01000194) [194.25.187.226] connect 194.25.187.226 port 3149 220 X1 NT-ESMTP Server imail.bechtle-online.de (IMail 5.05 6-1) QUIT 221 Goodbye 08:18 19:09 SMTPD(009A0164) [194.25.187.226] connect 194.25.187.226 port 3158 220 X1 NT-ESMTP Server imail.bechtle-online.de (IMail 5.05 7-1) QUIT 221 Goodbye 08:18 19:10 SMTPD(00AB0164) [194.25.187.226] connect 194.25.187.226 port 3167 220 X1 NT-ESMTP Server imail.bechtle-online.de (IMail 5.05 8-1) QUIT 221 Goodbye 08:18 19:11 SMTPD(00B30164) [194.25.187.226] connect 194.25.187.226 port 3176 220 X1 NT-ESMTP Server imail.bechtle-online.de (IMail 5.05 9-1) QUIT 221 Goodbye 08:18 19:12 SMTPD(queue run) 9 0 9 08:18 19:12 SMTPD(fqr) no prog D:\IMAIL\imailsrv -q 08:18 19:12 SMTP-(0000015A) D:\IMAIL\spool\Q0095aed.GSP 08:18 19:12 SMTP-(0000015A) processing D:\IMAIL\spool\Q0095aed.GSP 08:18 19:12 SMTP-(0000015A) Trying compass-es.de (0) 08:18 19:12 SMTPD(00C00164) [194.25.187.226] connect 194.25.187.226 port 3188 220 X1 NT-ESMTP Server imail.bechtle-online.de (IMail 5.05 10-1) QUIT 221 Goodbye 08:18 19:13 SMTP-(0000015A) MX connect fail "212.223.4.49" 08:18 19:13 SMTP-(0000015A) requeuing D:\IMAIL\spool\Q0095aed.GSP R0 T11 08:18 19:13 SMTP-(0000015A) finished D:\IMAIL\spool\Q0095aed.GSP status=3 08:18 19:13 SMTP-(0000015A) D:\IMAIL\spool\Q048eec0.GSP 08:18 19:13 SMTP-(0000015A) processing D:\IMAIL\spool\Q048eec0.GSP 08:18 19:13 SMTP-(0000015A) Trying compass-es.de (0)   Tried to connect via telnet to 212.122.129.2 and 212.122.129.6 on port 25 - works fine.
