CiviCRM Community Forums (archive)

I've been using CIVIMAIL successfully for about 6 months. Up until today i've been able to send out newsletters successfully. I've tried sending a newsletter this evening and got the error message below. Not sure why it is appearing. I searched on the forums for a like issues to pursue a solution. Tried a few things--basically just double checking configuration, and i'm still getting the error.

My SMTP settings under Administer> Configure > Global Settings > Outbound Email sends successful tests.

I've been making stand alone PHP pages outside of joomla using mysql. Would this have an effect on that?
