Hi All, I had this problem where one person in a company couldn't send an email to the person sitting next to them. Both sender and receiver were using the same company domain for their emails, both sender and receiver had the same smtp setting (that of their ISP). Reason: the mail server of the ISP had been blacklisted by spamcop. Solution: add the domain to /etc/rblbypass which (I understand) means that if the sender domain is the same as the recipient domain, don't run rbl checks. Two points I'd like to make 1. I reckon it would be a good idea for all domains to be include by default in /etc/rblbypass. Makes sense, doesn't it, for 'internal' company mail? Is this possible to setup? 2. It would be good if this feature were a checkbox options in WHM, and not buried in a command line file. Comments anyone?
