Hi. I've been playing with other systems today and they all rewrite the Message-ID header which make them unusable with the lists. I think I'm going to set up a cheap relay on another cloud provider as for the £20 per month I am paying for Sendgrid its more than the VPS itself and I can pay less for professional list hosting per month. If it weren't for the list I think Sendgrid is the best option for individuals or if your app is sending out the occasional message for example my Mastodon instance sends out a couple per day.

Unfortunately a lot of the issues with deliverability comes from how many emails your IP have successfully sent in the past x number of hours. When I ran larger email lists I had absolutely no issues in delivering to the top providers. Its only since the lists moved to a new home I had deliverability issues.
That's insightful, thank you. I suppose their argument would be that a substantial volume of messages is needed to collect strong evidence of a server's maintaining appropriate sending policies. It may be worth noting that Microsoft 365 is now sending DMARC aggregate reports regularly; other large providers were already doing so. _______________________________________________ Blind-sysadmins mailing list -- blind-sysadmins@lists.hodgsonfamily.org To unsubscribe send an email to blind-sysadmins-leave@lists.hodgsonfamily.org
