Continuing the discussion from Abiding by Amazon SES's "14 emails per second" maximum send rate:
I’ve been thinking of switching my SMTP relay to the generous Emailit plan of $20 per 100,000 messages, but they’ve recently set a rate limit of 2 emails per second.
Reviewing topics that ask about rate limiting / throttling digests and emails, the only available setting seems to be DISCOURSE_MAX_DIGESTS_ENQUEUED_PER_30_MINS_PER_SITE.
I don’t know if I should assume that the value for that is distributed exactly into an X-per-second rate.
And it’s only digests – I’d have to account for other surges like watching-first-post blasts, etc.
With the info I have, it doesn’t feel workable to use an SMTP service with a rate limit. Is there anything reassuring that I’ve missed?
