Server move - all working except inbound email
I moved my servers to a new colocation, I changed IP numbers both throught the admin pages and also via phpMyAdmin.

DNS not done on ispconfig box is done by third party, and was updated.

To date everything is working fine except inbound email. See maillog sample:

Jan 16 10:22:35 mail postfix/qmgr[4037]: 029071C071D: to=<>, orig_to=<>, relay=none, delay=1, status=deferred (delivery temporarily suspended: connect to[]: Connection timed out)

Any ideas/insight would be appreciated.

Is this "" the new hostname or the old hostname?

It is neither my new or old hostname. The hostname has not changed, just it's IP address. That appears to be a resolved name from a DNS server.

I've not yet published a reverse DNS for this server. hmmmm

But if I do :

I get: domain name pointer

which looks right.

Any other ideas?

As far as I see there's no PTR record for your new IP address yet:


mh1:~# dig -x

; <<>> DiG 9.2.1 <<>> -x
;; global options:  printcmd
;; Got answer:
;; ->>HEADER<<- opcode: QUERY, status: NOERROR, id: 32760
;; flags: qr rd ra; QUERY: 1, ANSWER: 1, AUTHORITY: 0, ADDITIONAL: 0

;    IN      PTR

;; MSG SIZE  rcvd: 84

But I think your error is caused by DNS not being updated fast enough. DNS changes can take up to 72 hours until they are propagated, so maybe you might have to wait a little bit longer.
