When adding new users to the blank domain via the web interface and GUI, server will generate return addresses based on the first alias in the list, rather than appending @_nodomain;
Changed the way how chunks of IMAP responses are sent. In earlier versions, there was an option (Tools - Options - Advanced - Use IMAP Streams) to send the data either line by line, which was slow, or, as a stream, in one shot, after entire data was ready, which was causing timeouts, if folder had several thousand messages. Now, that option is gone, and data is transmitted in "chunks" of 8192 bytes (Pro version, affects only IMAP);

This is the major update, probably, since introducing IMAP. There is a significant change with the web interface of Pro version, also, we did considerable work with optimizing the server, so, now it should be able to handle more users, more connections.

VERY IMPORTANT!!! Beginning from this version, web interface of Pro version is able to handle multiple folders, which means, earlier versions of web templates do NO LONGER work with this version.
