I dont know how many people here are advanced in using older macs, as they are in also using older Amiga's. but..
I am trying to send email with Eudora 1.5.5 on my LCII which is on the internet right now, browses and such, but every time I try to send a message from Eudora I get "the address suchandsuch@something.com is incompatible with your SMTP server, and will not send until it is changed." Now Ive tried multiple Pop3-SMTP services and I come up with the same problem.
