I’m testing out a new relay service, Mailgun (https://www.mailgun.com/). So far it seems to be running well, but if any of you on the receiving end of things notices a problem, please let me know.
One other issue is the cost: it’s free if the total # of emails sent is under 100K, but gets expensive above that. Last year the highest number of emails sent in a month was 280 in May, which is about 133,000 total emails, and that would have cost $120 for that month (ouch!). So I’m not sure if I will keep it, but it’s worth a trial at least.
I’ve tried several approaches to get this to work, but no luck. They have a service they call “Mailing Lists”, which would allow me to send one message and have it sent to everyone on the list, so that sounded promising. I worked out a script to sync the subscription status on my server with the Mailgun lists, but tried sending a few test messages. Turns out that they wipe out all existing header information, and replace it with their own, which would totally break the archives, since the Message-Id: header is key to threading. It also strips the Reply-To: header, making it impossible to reply to the list automatically.
So we’re back to me sending the mail directly from my server. Apologies to all whose ISPs block me.
