If the messages are not customised, why not use a mailing list server like LetterRip?
Or you could write a message file for the outgoing mail folder of SIMS (I imagine it's
like EIMS in this respect) plus a list of recipients and let the server do the hard
work
The bottom line is that if you expect Tango to send each email as a unique mail to
SIMS (or EIMS, or anything else) then the system will always fail under load
eventually. If you're rolling out this system to unknown network setups you might be
better omitting the SMTP Tango --> SIMS step altogether
The EIMS list has seen discussions of this kind in the past, as has the LetterRip
list. V4 of LetterRip will allow customised messages per-sender and there has been
some discussion about backending it onto a database. I'm not sure how developed this
plan is right now but the words SQL and ODBC were mentioned...
Even without this you could output a subscriber list as tab-delimited text, import
that to a LetterRip list and send the mail to that list. Job done!
