After some users have had issues recently, I’ve finally gotten around to putting in place a better solution for outbound email from this instance. It now sends out via Amazon SES, rather than directly from our OVH VPS.
The result is emails should actually get to more people now, rather than being blocked by over-enthusiastic spam filters… looking at you Outlook and Gmail.
Nope, I’m a fool. SES is in sandpit mode, it won’t send to anyone but my identities. Rolling back until AWS move me to production :(
It’s still potentially a solved problem. One that has been most annoying.
