Mails not being sent

[Daskew]

Hi,
Dont know whats going on here so was hoping someone might be able to shed some light on it for me.

Basically emails are saying they are being sent but they arent actually being delievered. They are deleivered though if they are to a domain on my own server but nothing externally.

I have all the correct ports open as this was working before. I cant remember changing anything except adding a catch all to one of my domains about a week ago. However the mails not being sent are affected on all my domains not just the one i added the catch all to. Cant see how adding a catch all would affect it anyway but thought i'd mention it as you never know.

Ive checked the logs and it says the mails are being sent, nothing is bouncing back either.

Anyone got any clues because im stumped?

just to add as well, mails are being received fine and ive restarted exim.

Another update, mails are being received on some email address's as we have sent one to a BTinternet address and it was delievered.

Using the url from your profile, your name servers may have something to do with it. From looking at this information from dnsreports.com it would appear that you have a name server not responding. Some mail servers may reject incoming email when they can get valid dns reponses. Veiw the report here: http://www.dnsreport.com/tools/dnsreport.ch?domain=world-pool.co.uk

Check and make sure that all of your name servers are indeed working correctly.

Hi,
Thanks for the reply.

I know about this and have found out that it is because my router can open the same port (53) for different IP's provided they are not open at exactly the same time.

Is it possible that I can tell exim to deliver mail using a different SMTP server rather than using it's own? Before I used DA I used postfix and could tell it to either deliver mail directly or use another SMTP server. This way I can use my ISP's and wont have the problem.
