Thread: HELP! SMTP + IMAP +Domain setup

situation:

have smtp + imap server. server behind firewall correct setting work. server connected internet via static ip comes isp (called hereafter isp). also, have web domain registered under company (called hereafter domain provider). dns settings of web domain setup guides internet (a, mx, cname).

problem:
server working fine in first weeks of operation, problem occurred when domain checkers blacklisted me.

sample domains mxtoolbox. have found out isp did not give me rdns (reverse dns) domain. domain checker tool found.

result, outgoing emails blocked domains such google, yahoo. incoming ok, no problem there.

ideas considered:
1) outgoing email pass through domain provider not know change server, dns settings
2) ask isp enable rdns

ideas appreciated.

start out running own dns server. put mail server canonical name whatever ip reverses to. should pass rdns qualifications.
