unable to relay on sendmail
Hello folks!!
i am running FC7 with sendmail-8.14.1-4.2.fc7. this is my problem. I have a webserver on my fedora, but I need to relay all the email from fedora to my exchange 2003 server, I have tried almost everything and I not able to make it work, I hope and you can help me to fix this problem. Here is my sendmail.mc divert(-1)dnl dnl # dnl # This is the sendmail macro config file for m4.

OK, just quickly looking over your config files, it looks like the domains are local to Sendmail and Sendmail will try to deliver the mail locally rather than sending it on to the exchange server. You need to see how Sendmail will handle the mail delivery by using the address test.
sendmail -bt will put in in the address test mode. 3,0 someome@example.com will show you how Sendmail will route mail to this person from the outside. Then you try to make changes to your cf file to see if Sendmail will route things differently. |
Thank you for your response.
I did that, and here is the output: ( sorry, but I dont know to much about sendmail.) this is go to gmail.

Please help! thanks |
Well,
I got it working!!! there is only one change to make the relay working on exchange. on sendmail.cf, we need to add the smart host, and that's it!!, no access table modification no relay-domains.... no local-host-domains..... I just add my smtp server to the cf file, and on my mailertable, and that's it!! well I had to add the FQDN on my hosts file too. Thank you everybody!!! |
I was about to suggest this!
