In Japan, 3rd-level public suffixes are quite common, taking the form:
...jp.
For example:
hospital.hekinan.aichi.jp.

to avoid overload like query blocklists but to analyze
emails use

Generally, no, because you will reject legitimate domains
that just look like subdomains, e.g. *.co.uk,

/email@office/ REPLACE From: Office
/email@hospital/ REPLACE From: Hospital
With the above, the replacement works fine for multiple lines.
