Thanks Dirk for considering my situation,
Well I have 4 systems.
- system 1 is installed with zimbra whose IP is 192.168.2.108.
- system 2 is the live web server whose IP is 192.168.2.101
- system 3 is a database server whose ip is 192.168.2.104.
- and system 4 is a backup of live web server 192.168.2.102
All the four servers are connected to an external router. Now system 2 and system 4 has sendmail installed which are configured to give all its mails to system1 on which zimbra is installed for final sending. Now what is happening that when I send mail by accessing web-console installed on system1 it get failed but when I try to send mail to the same email add through sendmail installed on system 2 or 4 its going just fine with no problem.
above is the maillog of system2 which clearly shows that the mails are indeed being routed through system 1 on which zimbra is installedJan 27 19:21:15 web1 sm-mta: o0RDpDv1014067: to=<firstname.lastname@example.org>, ctladdr=<email@example.com> (0/0), delay=00:00:01, xdelay=00:00:01, mailer=relay, pri=120341, relay=mail01.saptsati.com. [192.168.2.108], dsn=2.0.0, stat=Sent (Ok: queued as 2E860588AF)
I am sorry for that. I have given the sendmail maillog of other system in my previous post. I should have given it in my first post itselfYou've given no evidence that your mail is going through the same server, you need to do that and perhaps provide some information from the log files to show it going through Zimbra.
Please don't take me wrong. I was saying the game in general. I know I have problems with my IP also I will take it after this issue get resolved. But the only thing which is making me surprised that when both the mails are sent through same machine why the one mail is ok and other is not.It's not a case of blaming a 'text book reason', you actually have a serious problem with your IP address. Just for clarification, I'm not trying to win any game whatsoever.
