I imagine that they stopped doing this when MIT moved to centralized (Office 365-based, gack) mail infrastructure rather than running their own (with the attendant large reductions in overhead, functionality, stability, etc.) That said, this is probably the exception that proves the rule, as keeping the sendmail.cf changes up to date was a constant sink for work even before the advent of dkim/dmarc/spf/eieio. <shakes fist> ~Chad
