# giving F=S will fork mailers setuid root. My reading of the code and docs for sendmail says that F=S makes it setuid to the recipient if possible when doing delivery. The doc says this is useful if sendmail runs setuid. I'd say! But sendmail seems to be setuid to 1 (daemon) otherwise. In no case I can find will sendmail deliver anything or exec anything while it is uid==0 || euid==0. # This came up somewhere else where someone (I'll leave him nameless) said # he was about to send the same comment to me and, upon glancing at his # sendmail.cf, saw that in fact the S flag was present in at least one mailer.. I'll name him: me. I checked our .cf and saw that we don't use F=S anywhere and I asked (this was on another mailing list sorta like this one) whether anyone anywhere used F=s on Mprog and if not why not. I repeat the query. Paul
