My group email and subscriber notification email suddenly stopped working. I've read the above post re Emails Not Sending but my issue doesn't seem to be my service provider - Go Daddy. I talked with them and I am under their daily group send limit and there are no restrictions in the from address. I'm using MAC mail and they think maybe it's an issue with MAC mail.
Could you please shed some light on what could be happening and if you think it might be MAC... Thanks. Joanne
