Hello,
I have one customer who I have been invoicing for a long time. Recently the emails sent via ReckonOne have been undeliverable and the reason provided is:
550 5.7.1 Sender ID (PRA) Not Permitted
The emails are not going to the customers spam folder and nothing has changed in terms of their email address. This is the only customer I am having this issue with. Previously there was not a problem.
Thank you
Melissa
