This bug can be closed, simply as an MX record is for a *MAIL EXCHANGER* and that thus doesn't not point to a host which supports the 'finger' service.
Now, a feature to ask for SRV record support would be a good thing, but as no other clients support this and nobody has actually configured it that way, it will never ever be used anyway, thus also totally useless. Greets, Jeroen
