I'm seeing long periods where MailDelivrerToHost isn't mentioned in the logs even though there are plenty of emails being spooled.
How can I find out what's going on? I've increased the delivery threads to 20 and the spool threads to 200 but if anything it's made it worse. Customer now screaming at me. E.g. 2025-08-01 13:11:41.199 [DEBUG] o.a.j.m.i.JamesMailSpooler - ==== End processing mail Mail1754053901091-441b1ec5-bce3-40ee-af08-94d5a109240e-to-gmail.com ==== Then... nothing.
