We have a new client that is having issues with their reservation software sending email confirmations. The same computer that the program is running on can send emails out from Outlook Express without any issues. We do not have any other clients having problems and it seems the issue is only happening with the reservation software but the reservation software vendor says that the issue is not on the end. The software could send out email confirmations on their previous host without any problems.
Have any of you ran into this problem with the error message "incorrect state for auth" before and if so how did you resolve it?
Thanks in advance!
