SpamAssassin detects spam, it is not designed to tho content modification.

Anyway, this is a bad idea, for example you can cause changing middlesex to
middle--- or sextant to ---tant. You would also invalidate DKIM signatures.

Try avoiding this clbuttic problem.

not with spamassassin.

Perhaps filters like amavis, mimedefang, milter-regex or similar support
this.

Such a thing is not possible in SA, because SA has no mechanism for
arbitrary content modification. When used in a milter like MIMEDefang or
MailMunge, SA doesn't even do any header mods itself but rather relies
on the milter to do it.

As others have said: substring replacement in email is an unwise tactic
that proved its utter uselessness in the '90s.

Aside from the fact that this would do active damage to the
comprehensibility of some perfectly legitimate messages, it would
invalidate any sort of authenticating signature (DKIM, PGP, S/MIME,
whatever)
