For years I've had a simple HTML/PHP email contact form on my website, which if properly completed sends me the visitor's message with their email in the Reply-To field so I can easily respond. This month Thunderbird's handling of these messages changed. It correctly shows the Reply-To address in the message pane, but clicking Reply gives a compose-new-message window with the To address (i.e. mine) copied from the original message and Reply-To set to the visitor's email.<BR /><BR />On further investigation it seems that this happens only when the From address of the message sent by the script is recognized by Thunderbird as one of my "identities". If I substitute an "unknown" address, Reply now correctly replies to the visitor's email.</P><P>Is this the intended behaviour?</P> Sat, 13 Sep 2025 13:54:45 GMT https://connect.mozilla.org/t5/discussions/reply-to-oddity/m-p/105356#M40777 ansiblemag 2025-09-13T13:54:45Z https://connect.mozilla.org/t5/discussions/reply-to-oddity/m-p/105379#M40783 <P>As it worked before, you could file a&nbsp;<A href="https://bugzilla.mozilla.org/enter_bug.cgi/" target="_self">bug report.</A></P> Sun, 14 Sep 2025 00:02:30 GMT https://connect.mozilla.org/t5/discussions/reply-to-oddity/m-p/105379#M40783 siffemcon 2025-09-14T00:02:30Z https://connect.mozilla.org/t5/discussions/reply-to-oddity/m-p/105474#M40799 <P>Thanks -- I didn't see that option in Thunderbird Help.</P> Mon, 15 Sep 2025 16:32:56 GMT https://connect.mozilla.org/t5/discussions/reply-to-oddity/m-p/105474#M40799 ansiblemag 2025-09-15T16:32:56Z
