I am facing a problem in my SMTP connector. In brief i have an SMTP connector in that i have in address space Address " * " and cost is " 1 ".
Now i have created one new SMTP connector where in address space address is " gmail.com" and cost is "1" it was working fine for few days but now in queues this queue is getting generated "'Messages with an unreachable destination' queue" and there are about 150 mail in it with delivery failure.
I have only few users who is going to use this connector.
Kindly provide me the solution ASAP
