Palm Pre no PLAIN SMTP authentication, only doing LOGIN?
First impression with the Palm Pre: Did not want to send email. After some excessive SMTP server debugging and logging (not that strait forward if the connection is SSL encrypted, so no easy packet sniffing to see what’s going on) it turned out the Pre did not honor the available, offered authentications. Defaulted (hard-coded?) to old-school’ish LOGIN.
Getting the SSL root certificate onto the Pre was also a little Google exercise. There is a “Certificate Manager” hiding in the Application List (in the top-left context (Preference) menu). But as the Pre did not download the file (displayed it in-line in the browser) I had to copy it form a real computer via the USB storage mode. Import it thereafter, … A “do you want to trust the cert: yes/no” dialog (like on any desktop e-mail app or the iPhone) would certainly be enough, and way easier.
