Unfortunately, that will destroy the default export_environment setting with MAIL_CONFIG and perhaps more that is needed to make pipe-to-command-to-sendmail content filters work. Other approaches: -o { export_environment ,= HOME=/some/where ...} I haven't figured out how to make += etc. syntax work consistenly in all cases. Minor: does not derive the HOME setting from the user= attribute. directory=/some/where home=/some/where Makes fully explicit when HOME is exported and when the chdir() is done. Minor: does not derive the HOME setting from the user= attribute. On the upside, that gives maximal control over what happens (element of least surprise). directory=HOME Make the value 'HOME' special (take the user= attibute value, look up their home in the passwd database, then chdir() and export as HOME). Ugly, but avoids introducing surprises into EXISTING behavior. Looks like adding a home= attribute has the least element of surprise.
