Added support of STARTTLS (STLS) command for SMTP, POP3, IMAP, and SMTP relay and delivery, which will allow secure, fully encrypted connections, when possible;

Optimized delivery speed. In earlier versions each "tick" which was checking whether messages were in the outbox queue, was picking up only one message at a time. Now it will attempt to pick MaximumAllowedThreads-ActiveDelivery threads messages, which should considerably increase deliver speed;
Optimized SEARCH and STATUS IMAP commands. They appear to be used very extensively by Android, and (not that extensively, but still) by iPhone. Now users who use mobile phones to access their IMAP accounts will see considerable improvement;
Optimized STORE IMAP command. Before storing of IMAP flags was occuring one message at a time, which seemed to be fine with SQL server, but proved to be slow for SQLite... Now it happens with single SQL call.

Fixed a bug: when using IMAP via Firefox with "When I delete a message, move it to Trash folder" option, marking messages in the trash folder was causing high CPU usage, and was taking some time, making the server pretty much non-responsive. The problem was happening only when using SQLite.

Fixed a problem with web interface - was showing only first page of messages, and would not switch to other pages; In order to fix the web interface, mail server itself has to be updated;
When installint initially, was still using SQLite, even when SQL was requested;
There was a problem with switching from SQLite database engine to SQL server database engine: the SQL database was not being created;

5/23/2011 5:53:55 PM

The server no longer requires Microsoft SQL Server. If SQL server is not found, it will use SQLite engine, which does not require separate installation. If SQL server is found, then user will be prompted whether he wants to use it;
Made other improvements, such as, now mailbox rebuild indexes orphaned records, rather then deleting them, also added an opotion to increment UIDL validity of folder (both on the Mailbox viewer box);
Made minor improvements on web interface;
