@jdaviescoates Well, this is what I do for distribution list and it seems to work fine with Gmail addresses. But I have to say it isn't really a replacement for Cloudron lists. I find the current email situation really quite tricky on Cloudron, given:
issues with delivery on forwards to some providers like Gmail
issues with delivery when using an external SMTP (likely related to point 1) when trying to overcome bad IP rep (which with MS domains is a recurring issue with MS stupid IP range bans).
For work I have to now consider moving all our mailboxes out of Cloudron...which I would really want to avoid because of:
faff
because I love Cloudron and wanna promote it (but my users are getting pissed because of email problems).
@staff if you don;t really want to focus of changing the mailing function on Cloudron for now (and I totally respect and understand that this may not be your priority), can you advise on a working solution to use a address@domain.coop (with domain.coop being the Cloudron domain) which can be use as a list, where:
some mailboxes on this domain being hosted on Cloudron (so the MX has to remain pointing to the Cloudron server)
and while using an external SMTP server to ensure reliable email delivery
