|When you look at the full headers of the email received, having sent it

I have no idea of your boxes really (i did not even know OpenBSD
Mail supports -r), but my Mail clone (s-)nail documents (note
especially last paragraph; bit silly since standouts are missing):
-r from-addr, --from-address=..
The RFC 5321 reverse-path used for relaying and delegating mes-
sages to its destination(s), for example to report delivery er-
rors, is normally derived from the address which appears in the
from header (or, if that contains multiple addresses, in
sender). A file-based aka local executable mta (Mail-Transfer-
from,sender,mta: variables
Agent), however, instead uses the local identity of the initi-
ating user.
When this command line option is used the given single ad-
dressee from-addr will be assigned to the internal variable
from, but in addition the command line option -f from-addr will
I think sendmail used -r, but that ship sailed long ago.
Do all MTAs support -r still / does OpenBSD mail _do_ pass -f?
be passed to a file-based mta whenever a message is sent.
Shall from-addr include a user name the address components will
be separated and the name part will be passed to a file-based
mta individually via -F name. Even though not a recipient the
`shquote' expandaddr flag is supported.
If an empty string is passed as from-addr then the content of
the variable from (or, if that contains multiple addresses,
sender) will be evaluated and used for this purpose whenever
the file-based mta is contacted. By default, without -r that
is, neither -f nor -F command line options are used when con-
tacting a file-based MTA, unless this automatic deduction is
enforced by seting the internal variable r-option-implicit.
All this not OpenBSD for sure.
Remarks: many default installations and sites disallow overrid-
ing the local user identity like this unless either the MTA has
been configured accordingly or the user is member of a group
with special privileges. Passing an invalid address will cause
an error.
Ciao.
