Hi.
Thanks for the recommendation on the Google Workspace. How did you set this up in terms of the domain, since I don’t want to use Google Workspace as the main email provider for this domain. Also did you have to set anything special in Mailman?
Thanks. Andrew.

I would definitely look for alternatives to SendGrid. I tried using them and had a very poor rate of people actually getting my emails, even when I temporarily upgraded to an expensive plan with a dedicated IP address. I'm currently hosting mailman in Google Cloud and relaying outbound mail through a Google Workspace account. It's working OK. The workspace account costs me $6/month for basically unlimited mail relay.

Sendgrid is maintaining the Message-Id header which is good for archiving. It is re-writing the Return-Path header though which means that bounce handling in Mailman won't work, but I think all the services do this in some way so I am happy to live with that for the moment.
How does it rewrite the Return-Path? Returned mail is not something that such a service would be able to handle properly (although they can help with apparently returned spam). If mail is legitmately sent and returned as undeliverable, only the author or their agent will know how to handle it. So such >services should provide some way to find out about returned mail.
An example: Return-Path: bounces+[Sendgrid GUID]-andrew=hodgson.io@em6096.lists.hodgsonfamily.org<mailto:hodgson.io@em6096.lists.hodgsonfamily.org>
Sendgrid provide information about bounces but crucially that bounce isn't forwarded back to the original return-path sender (i.e, Mailman).
A few people have pointed out they can provide list hosting at a cheaper cost than Sendgrid so I'm looking for alternatives again.
Andrew.
