I’ve almost finished the beta version of my mail archiving extension for vPop3.
Written in Python, it uses a MySQL backend to store the email message. At the moment there is no front end as the “getting-it-stored-asap” bit was more important for us. The code needs tidying and also needs to take mysql connection settings from a config file rather than being hard coded, but it works.
I just have to make sure that I can GPL it and I’ll have it uploaded to the site. I’ll also be telling the creators of vPop3 that this baby exists.
As far as I know there’s nothing that does the same job for any windows based SMTP servers, and I might just be creating a different version that will act as a transparent proxy between a server and the outside world. That, however, is a whole different kettle of fish.
