Add the Mail Server you are using
to Emmestech's List of Valid SMTP Servers

To prevent SMTP probing, Emmes Technology restricts access to our SMTP server to only a small number of recognized valid SMTP servers. The fact that the server you are using is not yet on our list does not, in any way, reflect negatively upon your server, but simply reflects upon the inadequacy of our list.

Please help us add to our valid-server list by filling in the name of the server you are trying to email us from and then pressing "Add to list!".


Please be patient.   All requests are processed individually by hand.   Getting on our list will allow you to deliver emails only to one of the small number of users at   It will not allow you to use as an open relay to forward emails elsewhere. Thank you for not sending us spam.
