After sending a user is shown a page showing communication between servers

I have the module working in that it is sending mail, but after a user sends a message a white page is returned showing what looks like the communication between servers. I haven't found any other issues related to this so I apologize if it's already out there. Here's a small sample towards the end of what is returned:

SMTP -> get_lines(): $str is "250 Sender accepted. "
SMTP -> get_lines(): $data is "250 Sender accepted. "
SMTP -> FROM SERVER:250 Sender accepted.
SMTP -> get_lines(): $data was ""
SMTP -> get_lines(): $str is "250 Recipient accepted. "
SMTP -> get_lines(): $data is "250 Recipient accepted. "
SMTP -> FROM SERVER:250 Recipient accepted.
SMTP -> get_lines(): $data was ""
SMTP -> get_lines(): $str is "354 End your message with a period. "
SMTP -> get_lines(): $data is "354 End your message with a period. "
SMTP -> FROM SERVER:354 End your message with a period.
SMTP -> get_lines(): $data was ""
SMTP -> get_lines(): $str is "250 Accepted message qp 21883 bytes 812 "
SMTP -> get_lines(): $data is "250 Accepted message qp 21883 bytes 812 "
SMTP -> FROM SERVER:250 Accepted message qp 21883 bytes 812
SMTP -> get_lines(): $data was ""
SMTP -> get_lines(): $str is "221 Good bye. "
SMTP -> get_lines(): $data is "221 Good bye. "
SMTP -> FROM SERVER:221 Good bye.
