Hi there, I am using James 3.8.2 / jpa guice on Windows. Customer says that users are complaining of email delays.
One example I identified in the logs - email was submitted here: 2025-10-02 16:25:36.052 [DEBUG] o.a.j.p.a.h.CommandHandlerResultLogger - org.apache.james.smtpserver.JamesRcptCmdHandler: [250 2.1.5 Recipient <xxxx@xxxx> OK] Then spooled here: 2025-10-02 16:25:36.202 [INFO ] o.a.j.s.SendMailHandler - Successfully spooled mail Mail1759422336090-388e03bd-1020-4389-a0f0-89e4c97747b7 with messageId <-1642525984.317.1759422335691@QUAN001> from qtxdemo@xxxxxxx on 204.75.15.226/204.75.15.226 for [xxxx@xxxx] Then dequeued for sending here: 2025-10-02 16:25:36.317 [DEBUG] o.a.j.t.m.RemoteDelivery - Sending mail to [xxxx@xxxx] on host Domain : gmail.com But not delivered until 5 minutes later: 2025-10-02 16:30:58.303 [INFO ] o.a.j.t.m.r.d.MailDelivrerToHost - Mail (Mail1759422336090-388e03bd-1020-4389-a0f0-89e4c97747b7-to-gmail.com) with messageId <-1642525984.317.1759422335691@QUAN001> sent successfully to gmail-smtp-in.l.google.com. at 172.253.63.26 from xxxx@xxxx for [xxxx@xxxxx] I've set spool threads to 200 and delivery threads to 500, but counting the delivery attempts between 16:25 and 16:30 there were only a couple of dozen. Any idea what can be causing this please?
