I occasionally send e-mail from the command line via Postfix, using a script containing the command
/usr/sbin/sendmail -oi -f <myaddress> -t <myaddress> < file In a recent instance, the body of the e-mail contained a line beginning with the word "From"; the sendmail program prefixed the line with the character ">" and a space (evidently interpreting "From" as a header line that needed to be quoted). This was more than just a trivial annoyance, since it rendered my digital signature on the e-mail invalid. I think I encountered a similar problem a couple decades ago using the "mail" command on a FreeBSD machine, but I don't remember any solution to the problem. Is there a way to tell the Postfix sendmail command not to alter any such lines in the body of the message? (I'm afraid I wasn't able to discern an answer in the man page for sendmail or by searching the postfix.org site.) Best regards, Greg Marks
