I'm not sure if i'm posting on the rigth place. But i suppose that admin have to do something with this issue.
I 've setup another POP account says email@example.com under Preferences wihtin my Zimbra webmail box. The purpose is to aggregate my various mailboxes within zimbra.
Now, my problem is when i want to reply to an email read from an extern mailbox, i would love to use firstname.lastname@example.org as sender address. But in the dropdown menu box near subject while writing an email, all accounts appear to be from my zimbra mailserver.
How can i fix this issue?
