Cant recieve external emails on ultimate centos 5.2 install

hi guys,

Got a problem with my postfix install.

I used Falcos superb guide on my last centos 4 serer and it worked sweetly. But I am not having the same luck this time with a new server!!

basically, I can recieve and send emails internally.
i can send emails externally.
but I cannot recieve any mails from outside to my email accounts on the server.

I am scratching my head big time and seeking help or guidance before I go insane!

The DNS mx record is set to

Maillog is not showing errors for incoming mails, its just not showing anything!!

I have attached some results from a few commands, the netstat -tap results have me a bit puzzled as there are a lot of things 'holiding'.. not sure if this is right!?

Also, the results for my

differ slightly as they are

Virtual.db is all updated

Also, I keep getting an email from root for a cron job saying

All help appreciated..

 

Please add server1.mydomain.co.uk to the mydestination line in /etc/postfix/main.cf and restart Postfix.

 

Thanks Falko

I have done this

but it has not made any diference

No errors showing in the maillog :/

 

One thing I have thought of...

The server was allocated with 5 IP addresses.

Only one of them is fine. (the main one listed in hosts file)

The other two I have added in my DNS provider as (subdomain) records dont seem to be working as expected though.

using nslookup the mail sub domain resolves correctly though :/

This test on the mailserver

Gives this

i added the mail.mydomain.co.uk to hosts with the corresponding IP to see if it helped. it hasnt!

and heres a snippet from the latest part of the maillog. I noticed that the cypher verification failed.....? the log is full of this,(the fail) and I only just noticed....

 

What did the mydestination line look like before you changed it?

 

I originally had it set to

which is what worked perfectly on my last centos/postfix server.

 

Then add server1.mydomain.co.uk at the end of /etc/postfix/local-host-names and use mydestination = /etc/postfix/local-host-names in your main.cf.

 

it is already Falco :/
Im thinking of removing and re installing postfix...!!

 

Do you still get this error?

 

Update!!
Thanks for your help falko

It is now working. I wasnt getting that error and it seems it wasnt the postfix config that was the problem.....----->>>>>

The problem I pinpointed was after doing an SMTP mailserver check online, which said the subdomain wasnt responding, it also wouldnt reply to a ping.

The server provider gives 5 IP addresses with it, and I was using a seperate one for my main site (the first one allocated/main one), and another for the mail server.(as I had it on my last server)

Even though the Ip is listed in hosts file (centos5) it is not working and when I changed the subdomain dns to point to the primary IP it is all working (email etc)

Going to need some further digging I think
