spost is very very old (it dates back from the original MH), but it was never documented (it was documented in the old MH FAQ). If you used that instead of sendmail/pipe, I suspect you put it in your .mh_profile 15-20 years ago and just forgot about it. The only reason that shell script exists is for those people who still had it in their .mh_profile. Just as a timeline ... the creation of sendmail/pipe and the spost compatibility shell script happened in nmh 1.6. The switch to the submission port happened in 1.7. --Ken
