smtp server error 1&1

Hello,

I don´t seem to get the newsletter plugin running. Having spoken with the support at 1&1, I set the following smtp server: mrvnet.kundenserver.de, port 25, no ssl

Then the following lines appear:

SMTP -> get_lines(): $data was “”
<br />SMTP -> get_lines(): $str is “220 mrvnet.kundenserver.de ESMTP Sat, 01 Mar 2014 09:18:49 +0100
”
<br />SMTP -> get_lines(): $data is “220 mrvnet.kundenserver.de ESMTP Sat, 01 Mar 2014 09:18:49 +0100
”
<br />SMTP -> FROM SERVER:220 mrvnet.kundenserver.de ESMTP Sat, 01 Mar 2014 09:18:49 +0100

<br />

What can I do?
