discourse not sending secure mail

[robe]

Right now discourse is not sending secure mail, which may cause rejection by some providers.

I think I should be able to use the 465 TLS port by changing port to

and setting:

DISCOURSE_SMTP_FORCE_TLS=true

Will try this later tonight.

I also think I need to change to lists.osgeo.org cause I don't think mail.osgeo.org has a cert to be trusted.

But I feel we should move mail.osgeo.org to a separate server anyway and switch everything (except lists.osgeo.org to that new server)

I was hoping I could change the config and do a fast docker start / stop, but I guess a rebuild is required for it to reread the config, so I'll wait till more off peak time.
