Time Warner Cable Webmail user ... cannot REPLY-TO ... Pegasus Mail user ...
Patience with me please ... I have tried to address this with TWC with little luck.
When I do Reply-To: which normally inserts some "quoting characters" along with original message into my email client (which happened to be a web client by TWC).
This all works for all my email sending buddies ... except the Pegasus mail user ... whose messages are coming through as "text/html" even though fairly plain.
How can I debug this problem ? Is it some bizarre character in the email ?
