Sendmail Configuration
I'm Redhat EL 3 with 1 domain name - www.4300.co.uk.
My server has the domain name as.4300.co.uk I'm trying to set up the machine to send email via sendmail. I know some of you may advise me to switch to another MTA, but for whatever reason I want to use sendmail. I've set up masquerading so that the email shows that its come from @4300.co.uk and not @as.4300.co.uk I can send mail out no problem, but the server wont accept incomming mails. I can send mail to another user on the box, provided the email address is 'user'@as.4300.co.uk. If I use 'user'@4300.co.uk, the email just gets held up at the main que with the message.....83.*.*.52 (IP of server) not reachable. Can anyone guide me in the right direction please. |
Sounds like your DNS server can't resolve the domain. Does adding the domain name to /etc/hosts help?
Code:
127.0.0.1 4300.co.uk |
You may also need to make sure that Sendmail is configured to relay mail for your domain. This is done by putting the domain in the /etc/mail/relay-domains.

Thanks for the replies, through another thread i've found that I didnt have the following uncommented..
DAEMON_OPTIONS(`Port=smtp,Addr=127.0.0.1, Name=MTA')dnl I've uncommented this and am now getting the following error..... ----- The following addresses had permanent fatal errors ----- <robert@4300.co.uk> (reason: 553 5.3.5 system config error) ----- Transcript of session follows ----- 553 5.3.5 83.67.67.52. config error: mail loops back to me (MX problem?) 554 5.3.5 Local configuration error I know my MX details are all correct, so where could the problem be ? |
Have a look at the sendmail FAQ at http://www.sendmail.org/faq/section4.html#4.5 - this is a reasonably common problem. It's also possibly a DNS problem according to http://www.experts-exchange.com/Netw..._21648629.html, but it's worth ruling out the config issue first.
