I am having a real hard time with sendmail and it is frustrating the hell out of me. I have installed and configured sendmail before and never had a problem. I cant figure out what I am doing wrong this time. As you all know there is alot of different files and settings to configure so I am not going to list all my configurations. If I "telnet localhost 25 " i get this:

[root@gw /root]# telnet localhost 25
Trying 127.0.0.1...
Connected to localhost.localdomain.
Escape character is '^]'.
220 gw.ultra-net.biz ESMTP Sendmail 8.11.2/8.11.2; Wed, 24 Apr 2002 09:13:51 +1000

So the service itself looks ok.....but if I try to send e-mail thru sendmail remotely like using outlook on a windows machine I get smtp socket 25 ssl errors(the windows machine is not behind a firewall) but if I use something like mail2web.com to check a mail acount on my linux box I can send but not receive mail. If any one knows of a really good how to with a good troubleshooting section it would help me out alot. If anyone requires more info from me on the configurations I am using let me know.

Suspecting two problems.

1. Check sendmail is listening only on localhost ??

netstat -an

if it is listening only on localhost then remove Addr part in the sendmail.cf file

O DaemonPortOptions=Port=smtp,Addr=127.0.0.1, Name=MTA

The line should be like this.

O DaemonPortOptions=Port=smtp Name=MTA


Enable relay for the respective client IP address.



Second problem:

In mail2web u are able to send mails not able to receive mails.

check imap and po3 is installed and enabled..

netstat -an

I have changed The line in sendmail.cf to look like your line and I have installed pop3 (qpopper) and it apears to be working fine, but when I netstat -an as you can see below it still apears to be listening to 127.0.0.1 (localhost)

[root@gw mail]# netstat -an

My relay_domains file looks like this:

192.168.1
optusnet.com.au

Any other ideas?

Hi..

U are correct.

have u restarted sendmail after removing the line ???


Siddiqu.T

I rebooted the whole machine....... still the same

Can u post ur sendmail file Options configurations (Daemon option). and status of netstat.

Have u enabled any firewall rules ??


Siddiqu.T

Hi ,

In above mentioned thread someone said that the line should read as

O DaemonPortOptions=Port=smtp Name=MTA

i disagree .... it should be

O DaemonPortOptions=Port=smtp,Addr=x.x.x.x, Name=MTA

substitute x.x.x.x with ur IP address .

Regards,
Xanthium.

i'll throw in my 2 cents here, though i could be way off.

i would try installing an imap server and making sure that port 143 is open on your machine. if you're able to send mail, but unable to receive it using an outside client, that's usually pretty indicitive of something being wrong with pop3/imap.

try and imap server and see what that does.

xanthium your a legand man.... ypu were spot on everything is working great. Thanks alot man.
