Ok so it can receive messages if i send it to firstname.lastname@example.org
. But when i send a message from the account, it says its from "email@example.com".
In ISPconfig, the 'Site' that hosts this email is "pkp.codecritical.net", so it would make sense that the email would be firstname.lastname@example.org
, but when I send, again, it says it is a different address.
