Description field for email aliases
Optional description field in "Email aliases" "Email Forward" and "Email Mailbox", so that a comment can be added describing the purpose of this alias/forward/mailbox eg. "this was created for subscribing to Whatever.com support , can be removed after ..." or "Temporary email account for testing ...., speak to .... to see if it's still needed" VARCHAR(100) should be sufficient
Rationale I'm adding a lot of custom aliases or accounts. When subscribing to unknown service I never give my normal email address, as they often keep spamming for years after I stop using them and very often sell their address databases. Before I started using ISPConfig I was adding comments into aliases file directly, with ISPConfig it's not possible as number of aliases grows they become difficult to manage.
