Presumably sendmail and binmail >are waiting for the user to unlock the mail file so they can complete Whatever your problem is, it is very unlikely to have anthing to do with 'sendmail'. Since 'sendmail' does not deliver to mailboxes, it doesn't ever lock them. It totally relies on other commands, such as binmail, to do the delivery. The only time that 'sendmail' delivers directly to mailboxes is when you use a filename as an alias. But even then 'sendmail' just appends the mail to the end of the file without locking. (The code comments imply that the code has to be able to dispose of problems fast, such as dumping mail in dead.letter when there are system problems). -- =*=*=*=*=*=*=*=*=*=*=*=*=*=*=*=*=*=*=*=*=*=*=*=*=*=*=*=*=*=*=*=*=*=*=*=*=*=*= Neil W.
