There is an optional configuration setting that limits what envelope sender Postfix sendmail or postdrop will accept. But I don't think that it would make this specific use case easier. https://www.postfix.org/postconf.5.html#local_login_sender_maps local_login_sender_maps (default: static:*) A list of lookup tables that are searched by the UNIX login name, and that return a list of allowed envelope sender patterns separated by space or comma. [...] The default is backwards-compatible: every user may specify any sender envelope address. ... This feature is available in Postfix 3.6 and later. There is more text that goes into the details, plus an example.
