Hello All,

I am new to IBM AIX and I want to send mail from the system.

But it is giving me following error;

"Failed to connect <smtpserver>"

So I tried to check this using "tn <smtpserver> 3535" and it told me "unknown host <smtpserver>".

But whenever I try telnet using Windows machine it connects successfully.

So I checked for sendmail service and it is active.

Will you please help me resolving this?

Thanks & Regards,
Ajit

Hello AjitPatil,
are you able to ping <smtpserver>?
if not - did you setup your DNS proper?

Port "3535" is very unusual to run a smtp-server (which normally runs on port 25).

Did you setup the smarthost (DS-Entry) in your sendmail.cf?

Cheers,

Hello Sir,

I am not able to ping or telnet to my smtp server and it runs on port 3535.

Also I don't know how to setup DNS or smarthost (DS-Entry) in sendmail.cf file.

Even I don't know how to find out the full host name.

Will you please provide me more details about this?

I'll be grateful to you.

Thanks & Regards,
Ajit

SendMail Configuration
1. Add exchange host name and ip in hosts file
2. Edit /etc/sendmail.cf and add at smart relay DS<exchange server hostname>
3. Edit /etc/netsvc.conf and add line hosts=local,bind4
4. Stop sendmail
5. Start sendmail
