Is there a way to reliably deliver emails using mailgun routes without getting this error message:
Failed: [email protected] → [email protected] 'Re: Sample Subject Line' Server response: 550 550 5.7.1 Unauthenticated email from yahoo.com is not accepted due to domain's 5.7.1 DMARC policy. Please contact administrator of yahoo.com domain if 5.7.1 this was a legitimate mail.

I like using mailgun routes because it meets my needs perfectly... but it seems that I can't reliably deliver mail to multiple recipients this way.
I'm trying to find a service that will allow me to
- create an email alias, [email protected]
- Send emails to [email protected] and have that single email delivered to 10-20 people with me as the sender and [email protected] in the to field (so "reply" goes to the sender and "reply-all" goes to everyone)
Mailgun routes fit this perfectly
I read their API docs and implemented a solution to read from our group database and make web calls to update my routes. Everything is great.
Everything worked great until I started getting the DMARC messages. Is there a way to avoid this? We're a small group (but dynamic) group and we'd like to make sending emails easy.
