Backup mx not delivering to new mx?

I've been using rollernet as backup mx for some of my domains. A couple of weeks ago I changed from having my own email server to using my isp's and hence changed the dns records to reflect this. At the same time I also changed from using my own DNS server to using my isp's.

Now when I check the mail queues here at rollernet I can see that I still have lots of emails in them. Checking the log I can see that rollernet/backup mx is still trying to deliver them to my old mx, which no longer exists and therefore is getting connection time outs.

What can I do?

Thanks/Max

It looks like you just need to update the IP address for SMTP Redirection. It's configured as an IP so it's ignoring DNS. Select the "Change Service" action from the selector and choose "SMTP Redirection (direct delivery)" to update the IP.

Thanks (strange though that not all my domains are setup as backup mx)

I tried to change to new ip but then in the log I got:
lost connection with 194.9.94.78[194.9.94.78] while receiving the initial server greeting

Tried to change to forward and then I got this in log:
host mailforward1.loopia.se[194.9.94.78] said: 451 4.3.5 Server configuration problem (in reply to RCPT TO command)

To me it seems this is something on the recieving end, can you confirm?

Yes, that's a problem with the server at 194.9.94.78 .

Ok it seems to be working again already (except that they use greylisting...)

Thank you very much for quick replies!
