CMS Made Simple Forums

Hello,

Used NMS in all my projects, in the latest project I get the following SMTP error:

SMTP server error: 5.5.1 Error: nested MAIL command

Does someone have a idea what this is?

Does the CMSMailer send test emails..?

If not you need to fix your SMTP settings, I never use that setting but I do use send mail and it always works for me...
