Bugs:

• Time outs were not properly working.
• Locks in some concurrent proccess.
• Lock the POP3 user when she is retrieving mails. That is: not allow the same user connected twice.

• The opened sockets where not properly closed sometimes.
• The bind process just binded to ONE of the existings net interfaces. If the host running the server had more than one card (like a gateway) there were problems to attach to it.
• A few more ..

New features:

• Multithreaded queued mails processor. They were sended one-by-one before this. Number of threads configurable.
• Multithreaded of the sending process of a single mail. This way, if a single mail has a lot of RCPT's they are sended using more than just one thread (like before). Number of threads configurable.
• A login feature has been added to the remote management. This way, access to that is restricted.
• Local domain configuration.
• Local IP configuration.

• A few more ..

New features:

• A new control thread has been added and will take over all the management like DNS cache, queues management, and checking if any mail is still pending.

Well, good perfomance but bad results. All the data of the mail were retained on memory during the transmission of the mail. Crash? Yes, we would loose the mails currently being transmitted ... Sorry. I have fix it up. Now, there is a temporary file that holds the mail's data. If the systems crash, the mails will be resent on startup. No mail losts.

It seems there are some problems with the DSN's and multiparts mails. This version will try to fix them.

There are also some things I have to do with the errors codes when a message is undeliverable. I didn't finish that.
