Distinction between next-hop and nexthop ?

[J Doe]

Hi,

I was reading the documentation for the smtp_tls_verify_cert_match parameter in 
man 5 postconf and noted under the “nexthop” strategy that both next-hop and 
nexthop are specified.

Example:

    “Match against the next-hop domain...”

    “When MX lookups are not suppressed, this is the original nexthop domain...”

Up until this point, I had been viewing them as interchangeable, but are they 
in fact referring to two different things/terms ?

Thanks,

- J
