Rails 4.1.6 Mailers Hanging

I just upgraded to rails 4.1.6 with ruby 2.1.2. None of my Mailers are working they are all hanging prior to, or perhaps during, rendering the templates. If I downgrade to 4.1.5 mailers work perfectly. From console If I break out of the hang using control-c this is the (important part) stack:

f = FooMailer.invite(FitnessClass.first, User.first, User.last)
FooMailer#invite: processed outbound mail in 94063.9ms
IRB::Abort: abort then interrupt!

Yep - it was an infinite loop in the Mail gem. This has been fixed by this commit and will be ok in version 2.6.2. Until then:

gem 'mail', github: "mikel/mail"

I found the problem to be in the Mail gem. If I downgrade to 2.5.4 everything works again. I didn't trace exactly what was going on but in version 2.6.1 the code was getting stuck in an infinite loop. I'd say this is more a work a round than a fix, but it's better than being stuck.

gem 'mail', '2.5.4'
