The project-imas.com mail server is declared as spam and rejected pretty much everywhere, and I haven't been able to find out why. The forum has been using a gmail address to send its mail since April 4th, and worked in my tests. Maybe it failed somewhere, I'll check.
EDIT: Mail seems to be sent just fine. But yes, if you filter messages from an @project-imas.com address, you'll have to change said address. The forum will now communicate from project dot imas dot forum at gmail.
