One way you might look at this...
What if your .ASP script simply launches a .VB or .JS script as a background
task, and then that script uses the JMail object for sending your list?
That's how I would do it. Launch it, log it, forget it.

| yes, but I'm sure that's Jmail own queuing directory, mananged by
| Jmail, and not Imails \spool queue. Maybe Jmail knows how to talk to

| proprietary queue and its SMTP client does its own remote deliveries,
| Imail is not involved.

|
| The Imail SMPTD receiving speed is pretty darn fast and a question of
| how fast Imail can spawn SMTPD processes to accept the mail from
| Jmail, and each process writing the its to disk.
|
| Is your .asp script calling Jmail per single message or per-bulk-list?
|
| If the former, I doubt your asp will time out. with the latter, it
| sure could happen.
|
| Not knowing what the asp time-out value is, it's impossible to say if
| the Jmail call will timeout, whether Jmail delivers to its own queue
| or sends to Imail. anyway, isn't the asp timeout value settable?
|
| btw, for Jmail to send to Imail, Jmail will have to have a "send all
| mail through a gateway" type of setting, so that Jmail doesn't try to
| deliver the mail the RCPT TO: but rather to the the Imail "gateway".
|
| The idea of the Jmail queue is that it can accept mail from your .asp
| script and return control to the script quickly without Jmail doing
| the actual SMTP delivery during the call, ie, asynchronous SMTP
| delivery, rather than synchronous delivery.
|
| Now if a single Jmail call is 10,000 mgs, then maybe asp is going
| timeout. Jmail just queues to disk and does the delivery later, but
| asp doesn't know about the queueing, but even with queueing, a
| 10,000-msg call to Jmail is gonna take time, maybe enough for asp
| to timeout.
|
| One aspect that favors Jmail-to-Imail is that you'll have Imail
| logging the sending, vs. what logging, if any, Jmail does. Having
| one log file to deal with is simpler, and Imail's logging probably
| has more info, and you can set the retry period and attempts in Imail
| rather than in Jmail.

|
| Well, that's why you're on Imail now. vbg
