Due to lack of interest on my part, time constraints, and various other reasons, I consider pop3lite dead, and do not want to continue its development.
POP3Lite 0.2.4 fixes RFC compliance, by adding support to correctly escape leading dots upon message transfer.
POP3Lite 0.2.3b was released today. It contains several fixes to the mailbox and file locking code, so the stale lockfiles should vanish. Also, it contains a fix for a well-hidden segmentation fault, which I could not reproduce without usign a debugger..
As usual in the stable release cycle, you should upgrade to this new version, available from http://pop3lite.sourceforge.net/
The new 0.2.3 release includes a fix for a possible dead-lock in the mailbox locking code; furthermore a new module (called iplog) sneaked into the distribution. See the release notes for more information.
This new release includes Solaris support and some fixes from Vesselin Atanasov. If you use POP3Lite on a high-loaded site, you should consider upgrading.
This release includes an important bug fix for occasional lossage when the data is larger than the TCP window. Thanks to Vesselin Atanasov <email@example.com> for noticing and fixing the bug.
I urge everyone using an older version to upgrade.
