I have always used a "reply-to" email address when composing/sending emails and it worked fine. I now get this error: An error occurred while sending mail. The mail server responded: Request failed; Mailbox unavailable. Please check the message and try again.

If i remove "reply-to" from composition, the email is sent without issues. I have multiple email accounts and with any placed in "reply-to, all generate same error.

Thanks Paul

many email providers are doing some questionable things with their email services. Thunderbird offers the option because it is mandated in the RFC, that does not mean you mail provider has to accept it. there is nothing binding on mail providers to even function unfortunately, let alone refuse legitimate information. Mostly I have fount it to be US based providers usually associated with Yahoo that do the weirdest things. But that might be a reflection on who seeks help on this international forum.
