Thanks Kenny,
For all that are interested, I have uploaded my 'IMAP Webmail System' to http://sdm.openacs.org/new-file-storage.
Feedback will be most appreciated. I'll be the first to admit that it is not perfect and there are still many issues I must resolve. Theres some documentation I wrote within the package which should be easy to understand.
Should there be any queries about the package, please let me know. All suggestions are welcome.
Thanks,
Ayman
