Sorry for just link-spamming, but this really is the best resource for SMTP banner info:

Judging by the name of the connectors I would guess the "default frontend", it sounds like the other connector might be custom specifically for outbound through a filtering or auditing tool.  I would recommend having it respond with your public mail address  (mail.company.com  is usually pretty close).  If you're very concerned about getting tagged as SPAM it would be good to start advertising SPF records and ensure you have reverse DNS records as well if you don't already.

I presume you are basing this information/change on what you see when you telnet in to Exchange on port 25? If so, then that banner information doesn't matter, despite what the tests at mxtoolbox and the like say.
That is for INBOUND email only, and will not get you flagged as spam. Therefore it should be ignored.

The FQDN that you need to check is the one set on the SEND Connector.
That should match your PTR, which should match a valid A record pointing to the external IP address of the server. To verify how the internet is seeing your server, use the technique I have outlined here:
http://semb.ee/bannertesting

SPF records can help, but their use isn't widespread enough to make a huge difference, unless you are borderline anyway when they can be the difference between being scored as spam or not. If that happens though then you probably have other issues with your configuration.
