I've been trying to send emails after setting up MBM and really have no idea what I'm doing wrong. I've read the directions! I upload my recipients from a .csv, have a blacklist I am successfully pulling from a remote database, have my server settings correct (it let me send about 20 mails yesterday before I got this message) - now, every time it tries to send a message, it looks like it's going to and then I get an error alert with this message up in the top corner. It'll try to run through all the recipients but keeps returning this error until I manually stop the job.
Any ideas? I'm so frustrated.
