• Hello,

    I’ve setup Postman SMTP correctly and have used it successfully for a while. Recently, I installed easy digital download’s product update plugin that sends emails to all my customers alerting them that a new update is available for download.

    So, the emails start sending. It goes through what seems to be a completely random amount, in the last case 89 and then stalls. I look at the Postman log and it is saying a 334 error. I know for a fact that I am logged into the account that I need to be logged into.

    To resolve the issue, I end up having to create whole know 02auth credentials and resume the send. I’d prefer not to have to do this every time – any idea what would be causing this? I’m running this on a VPS so there are no restrictions on my end.
