No, this too is not correct. The 'match' expands the second argument and
then treats it as a regular expression. From the manual:
The two substrings are first expanded. The second is then treated as a
regular expression and applied to the first. Because of the
pre-expansion, if the regular expression contains dollar, or backslash
characters, they must be escaped.
As such the '\.' becomes just a '.' after expansion. In a regular
expression a '.' is 'any character'. As such your first 'match' would
match, for example, 'epitoolsxcom'.
The easiest solution is to use the '\N' feature to disable expansion:
{match {${lc:$sender_helo_name}} {\Nepitools\.com\N}}
