ok i installed a modem router about 2 weeks ago at a local business which i provide tech support for ! problem! They have called me up twice in the past week stating they sometimes have problems with recieving and sending e mails, althought i think this might have been going on well befor i installed the modem router. They have said to me they have a domain name forwarding to another host! i have been to checkdns.net and they seem to have 2 mail servers 1 with each hosting company, is this possible to have 2 mail servers for the same domain name? And could this be the problem with sending and recieving emails through outlook?
