Removing incorrect email addresses from dropdownlist that autopopulates

Hello Team,

Do we have any options to remove the incorrect email addresses that auto-suggests as a drop-down list while composing emails? I have been looking for it under GAL settings, CoS preferences etc.., nothing helps.

We had "forget" option to delete such email ids if in case we type in-correct email addresses in the zimbra. Do we have any thing similar to this?.
