recently I have transferred an account to a second cPanel server. The DNS propagation has completed and all http, ssl and ftp traffic are now routed to the second server. Also, all external emails were successfully routed to the second server. So far so good. (Both servers are running in a DNS cluster, thus both has identical zone records)
But the problem I am currently experiencing is emails send from the first server (the original server) to an email address of the transferred domain are still routed to the email box located on the first machine.
Since all external emails are send to the email box at the second server, I doubt it is related to mis-configuration of the MX record for this particular domain.
Does any of you have any ideas of what is causing email send from the first server, only deliever to the email box located locally instead of to the email box at the second server?
