I reported a problem between PowerMail, Mac OS 9.1, and my Epson Stylus 740 to PowerMail Engineering back in May 2003 when we were still in 4.1.2, and also posted a note to the list about this issue a few months later. I _think_ I resolved the issue on my machine by making sure that Appletalk was not pointing to my Printer/Modem port, even when turned off. I don't recall having seen it under Mac OS 8.6 or 9.0.4.
