4. So, if the original Incoming mail server (
POP3) name was
my.mail.com and your username was
jdoe, your new username would be
my.mail.com:jdoe You can also include the port number of the incoming mail server, but this is not necessary if it uses the standard port of 110. There is no harm in including the port in any case, and to do so add it between the server and your user name like so my.mail.com:110:jdoe
