I don't know if this is a bug or rather an enhancement request:

if you have proxy rights to another groupwise account and have the
rights to send mails using this account, the sent mail will have the
sender address of this proxy account. Ok.

Backdraw is, that you have to proxy into this account, open the mail and
reply to it. After that you can switch back to your own account.

Much easier it is to have these emails forwarded to the own account and
handle them there. But here the sender address will be your own's
account address, not the one of the proxy account.

Problem is, that while *replying* you can not change the sender address,
as you can when you are *creating* a new mail.

This does not make sense to me, therefor I consider this a bug, not an
enhancement request. Or is there any option to do what I want?

Thanks in advance,
