I’m facing the same issue right now. Either I set up a new trellis instance or I extend the current one with an additional site.
@DaveNaylor can you tell a bit about your experience with the msmtp setup? Did everything work fine so far? Would you recommend doing it again? Do I understand it right, you then still use Mailhog but with msmtp instead of ssmtp?
Anyone else any recommendations how to handle the mail issue with multiple sites and one trellis instance? From reading through threads I guess a lot of people are using Trellis to have multiple sites running, so I guess there must be some more experience around this topic?
