the "for" clause was never very popular.
The default Exim configuration For Received: includes
a "for" clause for single-recipient messages.
Just like sendmail... for more than 20 years at least.
And likewise Postfix, since ~1997. So "for" is typically
supported on the mainstream open-source MTAs. Even Google
adds a "for" clause in at least some messages:
Received: from mail-sor-f73.google.com (mail-sor-f73.google.com.
[209.85.220.73])
