OK this is what I've found, and Imail support have confirmed it. What do you think? Have you noticed it?
On versions of Imail with the queue manager service, when Imail receives an ETRN command the queue manager starts an entire queue run for all mail in the queue (instead of just flushing mail destined for the domain in the ETRN). As our server receive a lot of ETRN requests from a number of customers, our server is doing a queue run approx every 2 minutes. This means two things: 1) Emails on our server for store & forward clients are being bounced back to the senders after about 2 hours (96 attempts) if the client hasn't connected within that period - this affects clients on dialup who restrict dialup to office hours and a small window at the weekend to prevent unnecessary phone charges. 2) Unnecessary workload on our server, in that Imail is doing a queue run approx every 2 minutes opposed to every 30 minutes. Some servers (exchange5) can even be set to issue an ETRN command with every outbound email! Because of this we've had to increase the number of retry attempts from 96 to 2400, so that mail will store on our server for up to around 48 hours. Crazy... I see this is as a bug, and still waiting for an ETA from Ipswitch.... What's your opinion?
