Over the past couple of weeks I have been moving the mailserver project closer to being ready for actual use and another milestone has been passed. I have now reached the stage where my hotmail and gmail accounts are collected onto the server and made availiable via IMAP.
This has not been without problems, I experinced a problem with mail not getting through the spam filter when sent from the local machine but working fine for the exernally received mail. This has now been resolved, although I have to admit I'm not sure how, mainly because I never fully isolated the actual cause of the problem. I suspect it was the system calling the spam filter multiple times whilst processing a single email. Now the next stage is to test how things work for a week or so and watch out for any more bugs.
There is plenty more documentation to write, every thing about the mailserver configuration is full of options to configure it and I want to make sure I have a reference for the future. I still might be on target for having all my other email accounts on the server by the end of the year.
