+1. A TXT record is seldom the right design choice, despite the trail of badly
designed protocols that attempted to argue otherwise.

However...

The right hand side of a SRV record is a hostname, not an email address.

(Trivially worked around in at least two obvious ways).

Also, support for looking up SRV records is even rarer than TXT or MX.
