Pegasus 4.8 Email Answer

I searched the Tiger Technology site for general information on email ports, and found:

https://support.tigertech.net/generic-email#incoming-pop3-email-jmp

 "Optionally, your mail program may support TLS security encryption (previously known as “SSL”) for incoming mail. If so, you can turn on that option. The “port number” depends on the type of encryption your program uses:"

    "POP3 with no encryption, or with “STARTTLS” encryption: port 110"
    "POP3 with implicit (forced) TLS encryption: port 995"

With three Security selections, and two ports, 995, and 110, here's what worked, yes, and what didn't, no:

Via direct SSL connect, 995* yes; 110, no
Via STARTTLS command, 995, no; 110, yes
Never, no port worked

I played around with the smtp setting, too:

Via direct SSL connect, 465 yes; 587, no
Via STARTTLS command, 465, no; 587*, yes
Never, no port worked

*I chose these settings.
