Hello, I was looking how to solve this for days, I also asked on IRC channel (Freenode) but got no answer. I called the company who sold me the license and they don't know how to help me... I will explain my problem: We have more than 70 hostings (for our clients) on some other hosting with plesk. We want to move all those hostings to a new server with cpanel but I found a problem with the mail username for mail clients (Outlook in this case). Let's say I have the client "Example" with the domain "Example.com" and I need to create the account "email@example.com". The default username for this account (for outlook configuration) will be "contact+example.com" or cpanel login. Well, what I need is to change that "contact+example.com" and make it "contact453" (for example), as it's on the other hosting so the client doesn't need to chang the username from his outlook client. I hope I can get an answer for this,thank you.
