no, that's the way it is. this is Imail's fixed param to avoid the "thundering herd" situation, to aovid overwhelming the recipient.Imail 7.13, the server is set to gateway all mail to an external SMTP box. One list in particular is set to 50 recipients per message. Every time this list is sent it kills SMTP, meaning SMTP will not accept any more connections. Simply resetting the service fixes the problem. When digging through the logs I'm seeing the messages are being sent to the gateway server in groups of 5 rather than 50, which I think is strange.
We see this 5-per-session with IMGate receiving in the outbound gateway role.
Imail "should" close at 5, and immediately open a new session without you having to kick it.
Try Scott's Queue thingy to see if it can keep sending alive.
For comparison, a list server like Ecartis / ex-Listar can have "SMTP queue chunking" set to 100 or 200 or more. This is how I set it up to inject over SMTP into postfix on the same box. Can send 60k msgs/hour.
