I get that Mail password rejection thing every now and then. Sometimes it takes 4 or 5 attempts before it sticks. Sometimes a Repair Permissions and a restart clears it up. Go figure. But NetSol's problems are due to their migration to a new platform (since having been taken over by Web.com): Delayed delivery of outgoing and incoming mail, having to run Connection Doctor to connect to their smtp servers, etc. They've been pretty quick to resolve these problems when they occur, but up 'til recently, SPAM was huge problem as they switched over to a new system.

Seems back to normal today.
