Some DNS Issues

Sometimes, customers, complaints that their emails delayed whenever they try to send them. It may happen when there is no reverse DNS record for the mail server primary IP. There is a need to Set reverse DNS record in the reverse zone file.

Sometimes, the customer, signup notification e-mail calls ns2 the primary nameserver and ns1 the secondary nameserver. This is due to the fact, that the distribution of primary/secondary DNS servers is done randomly to reduce load on particular DNS servers. As a result, a part of customers will have ns2 the primary DNS server.

There may be a problem, in which Support center hits an autoresponder and fills up with new tickets. To deal with such kind of problem, Get logged into the control panel as main admin

go to Settings -> TechSupport and

check "Don`t send confirmation emails for received Trouble Tickets."

In this case, no messages will be sent to confirm that support request received. If the Support Center got overloaded with new tickets, retrieve them with the search utility and apply mass closure/deletion.
