Allow logging in to webmail with alias credentials
Thank you for your input! We will consider this functionality in upcoming releases if it is popular. Everyone, please continue voting for this feature if you consider it important.
Please don't implement this feature. I often let my users create an alias for their mailboxes to use as 'main' email address so to obscure their real mailbox. Making it harder for attackers/bots to access mailboxes. As unfortunately login credentials are leaked or stolen from sites far too often.
