Mass email test works but actual mass email gives connection rejected in error log

Espo.ERROR: MassEmail#sendQueueItem: [500] Could not open socket: stream_socket_client(): unable to connect to ssl://gator3147.hostgator.com:465 (Connection refused) [] []

Hi there,
Please check your General Outbound SMTP configs in Administration -> Outbound Emails.

After I triple-checked I realized the cause...

it seems hostgator blocks if you send email too quickly in the same session (or maybe espo wasn't recycling the smtp connection). altering the processmassemail job introducing a delay worked for me.
