A WordPress plugin should be sending e-mails but it doesn’t send e-mails on your servers

On our shared hosting servers we’ve had to disable the mail() function for spam prevention functions. This resulted in several of our IPs being blacklisted and our team having to request IPs to be removed from the blacklist, that resulted in inconvenience to customers that are sending real e-mails. As a result customers have to use a PHP e-mail library so as to send mail, like SwiftMaier or the Mail category within the PEAR library that enables you to send mail directly over the SMTP server instead of through the PHP mail() function. Please make sure you use SMTP authentication with an e-mail account originated on your web hosting account.
