Incorrect or misunderstood information is not a lie. There is a difference. We certainly apologize for any misinformation given. LPCP, while very much like Cpanel and continuing to improve constantly, is not exactly the same and in fact has some things such as support for Innodb, additional scripts, and separate mysql and email servers which are not provided on our cpanel servers here.
At this time on LPCP:
Email Domain Forwarding - not provided
Default Address - not provided (often abused by spammers however)
Auto-responders - not provided but is on our list of upgrades to do
Email Filtering - not provided but Spam Assassin is.
Mailing Lists - phplist provided in webapps and you can manually install other mailing scripts
SpamAssassin - is provided. Set it up while creating or editing an email account.
Modify Mail Exchanger (MX Entry) - not provided but it has always been best to have us change MX records for you since there is an additional step that only we can do
