[ZendTo] Re: Centos Yum install

Mon Apr 18 14:44:12 BST 2011

Cheers Jules. 

If there were any doubt that I am a numpty, this proves it.  The fix
was:

service iptables stop. 

When I did that, all the attempts I'd tested with flew into my test
accounts. 

I hadn't allowed an exception for smtp in iptables. I didn't realise it
would try and connect to itself. 

Sorry...

Yes, that's fine. But it should only be listening on 127.0.0.1 and not 
on all interfaces, so this shouldn't be an issue.

In which case something is screwed in your DNS, IP or routing setup. I 
have used that sendmail.mc file countless times myself, and it has 
always worked fine. To say it can't route to 127.0.0.1 is rather bizarre

to say the least!
