Something _like_ that is possible.
What I would do instead is for the trigger to cause a record to be put
into a table that might be called something like "submit_email".
An asynchronous process (that might look for NOTIFY requests!) would
then rummage thru submit_email to find messages it needs to send.
That allows you to keep this sort of thing under some degree of
control.
- It means you're not concurrently spawning 157 MTA connections; the
"mail manager" only needs to open _one_ connection
- It means you have some ability to manage how much mail gets sent out
at once.
