finally found an email client that is small, fast and can send emails with a nonstandard email address. Now if I need to send emails from a “one off” account on my domain I can use SC-Unimail to enter the to/from and mail server and then send the email….It could also send mailbombs if you are naughty but in this day and age it would just get your account disabled in about 5 minutes so not really worth it for that!
