Is anyone implementing SRV records for either SMTP or for Submission
(i.e., SMTP SUBMIT extension)? Some talk about implementation raised
some questions:
- SRV is pretty redundant with MX for SMTP, though you could
conceivably use SRV to specify an alternate port number. Has anyone
attempted this?
- SRV for submission is an interesting way for an client to figure
out which server/port it should contact, but what exactly would the
query look like? Should you take the right hand side of your e-mail
address and query, taking me as an example,
_submission._tcp.qualcomm.com? Should you be looking up
_submission._tcp.4.3.2.1.in-addr.arpa (assuming your own IP address
is 1.2.3.4)? And again, has anyone tried any of this?
It would be nice if we had a convention for such a lookup.
