"JavaMail API 1.3.2 Release
The JavaMail API 1.3.2 release contains over 25 bug fixes and several new features, including: SSL/TLS support for all protocols, STARTTLS support for the IMAP and SMTP protocols, SASL support for the IMAP protocol and access to detailed SMTP error codes."
This has been demonstrated to add SSL support to fetchmail using a provider name of "pop3s" - <javaMailProviderName>pop3s</javaMailProviderName> in the config. Maybe we could also leverage other added features.
The bug fixes can't be a bad thing either.
