The folks at ConfigServer have finished their tuning and hardening of the server. Service should improve going forward.
There are some changes in how mail is handled on the server, and I’ll explain those as I fully understand them. MailScanner has replaced SpamAssassin as the front-end for spam filtering [although MS runs an instance of SA]. I’ll review the documents sent to me by ConfigServer and send them forward as appropriate.
Again, thanks to everyone for your patience at this time.
