My sympathies; this exact problem was the reason we CAPTCHA-ised our 
install of mailman and have to keep a very close eye on it.

It's really a shame there's so little open-source competition in the 
email sector these days; it all appears to have been hoovered up by 
Gmail, Office 365 and various spam (sorry - bulk email) providers.

Couple of random thoughts:

Does mailgun actually contain a mailman-alike product or are you 
effectively building one on top of it?

Will the mailman-style List-X headers remain?

Will the behaviour of the list w.r.t. things like routing of To:/Cc:'ed 
people change.

Good luck with the migration.
