    now i thought this could be a problem related to my dns mx settings so i check them and went to MX Lookup Tool - Check your DNS MX Records online run the diagnostics and everything turned out to be ok, but my clients mail to one specific e mail address keep bouncing any ideas ?


    Thank you in advance....

    So is the bounced email from your server or a remote one ? ie. is this inbound or outbound email.
