    Try "Send copy to" in the mailbox settings.

    Hi Taleman,

    Thanks for the update.

    I've tried that already with the same result sadly.

    When the email is forwarded it shows the correct "FROM" email address (the original sender) but the "TO" address is [email protected]

    Very strange

    That is the correct behavior; forwarding mail does not generally rewrite any message headers (nothing ISPConfig sets up would do so). When [email protected] hits reply, their mail client will typically look for a Reply-To header and reply to that address, and failing that will reply to the From address. Forwarding that ISPConfig sets up will not add a Reply-To header. At this point it somewhat sounds like an oddly-acting mail client, but what are the full headers of the forwarded message as [email protected] sees it?

    You might try toggling the "Copy during delivery" checkbox in the mailbox options and see if the behavior changes; that configures the forward to happen either in postfix (unchecked) or sieve (checked).

    Hi Jesse,

    Many thanks for the update. You are indeed correct :)

    How odd, I was trying this in Thunderbird (78.11.0) and it would not work as intended. I decided to give it a go on my iPhone after your post and it worked as intended o_O

    So it looks like a problem in Thunderbird?

    Perhaps I have something set wrong in Thunderbird?

    Wonder if Outlook works OK?

    Once again many thanks for your valued input
