Troubleshooting:Batch Mail error - 4.3.2 Concurrent connections limit exceeded

Question: When I send batch mail, some of emails failed to send out with error: 4.3.2 Concurrent connections limit exceeded. Why?

Version: 1.8 / 1.9 / 2.0

Possible Reason:

Multiple devices are trying to send email using the same mailbox at the same time and caused concurrent connections exceeded limit.


Solution:

1) Try again later to send those failed emails.

2) Try to reduce the Auto Count Mail Setting’s Maximum emails to send concurrently (For AutoCount 2.0). May put 1 or 2.

3) Please avoid using the same email address for multiple devices in AutoCount Mail Setting.
