Stripping Trailing Dots
Under some versions of sendmail, a successful conversion to a fully qualified domain name leaves an extra dot trailing the result. This rule strips that dot:
# strip trailing dot off possible canonical name R $* <@ $+. > $* $1 <@ $2 > $3
Note that this rule recursively removes as many trailing dots as it finds. Also note that the host part remains focused after rewriting.
