Host Does Not Support PHP Mail Function

For some reason I have been having some difficulty logging into our site, powered by wordpress, but that is somewhat beside the point. In trying to retreive my admin password, I used the ‘lost your password’ form. This message is displayed:

“The e-mail could not be sent. Possible reason: your host may have disabled the mail() function…”

James of the support department tells me “If it’s the php mail function we do not support that. You will have to use the smtp setting in wordpress if there is one.” He tells me there should be other mailing options in my settings, and that once they are configured correctly the mailing function should work properly.

If anyone knows how to configure these settings it would be immensely appreciated. Thanks. John
