Sometimes ListMailPro will stop sending and the error message is something about "a line with . alone" or words to that effect.
I don't have anything like that in any of the emails when this occurs.
ListMailPro then says to go to config, which I do and then click Resume
and sending continues, but sometimes it stops again with the same problem and sometimes it continues to the end without further interruption.
What causes this and what can I do to prevent it?
Thanks,
Rich
