In my IMAP profile settings I only have the server and username saved, so when I load Pmail it prompts me for a password to connect to my IMAP profile. I want a similar thing to happen when I send an email (at least my first email of the pegasus session). This is how Thunderbird behaves, but I can't seem to do it in Pmail.
In the SMTP security tab, if I don't tick any authentication boxes, pmail tries to send an email without authentication. Selecting "Login to the SMTP server using the following details" only works if I fill in the username and password; if I leave the pw blank, pmail doesn't ask me for it when attempting to send an email.
The closest thing I can do is fill in the pw field before sending an email and then manually delete the pw, which isn't great.
