Ive just set up my smtp mailer and am able to send site emails now (before, gmail were blocking everything going out by Dolphin mass mailer...)
But, I now get an error shows when I send an internal mail!
The mail still send, or at least I get the send confirmation message.
I also get this message though..
SMTP Error: Data not accepted. SMTP Error: Data not accepted.
Warning: Cannot modify header information - headers already sent by (output started at /public_html/mysite/plugins/phpmailer/class.phpmailer.php:586) in/public_html/mysite/mail.php on line 317
Any ideas?
