Normally, the "From:" header is created by the mail user agent (Mutt,
mail, ...). But according to the original sendmail man page, sendmail
may add a "From:" header if one is missing. Maybe your version of 'mail'
depends on this behaviour and expects msmtp to add a "From:" header.
Currently, msmtp does not alter the mail in any way (except removing a
"Bcc:" header if one is present). 

Maybe msmtp should add a "From:" header if none is present? I just
tested my postfix /usr/sbin/sendmail; it adds this header, too.
What do others think?

Is there any way to add custom headers to mails generated with 'mail'?
Then you could add a "From:" header yourself.
On my Debian system, this can be done with the -a option, for example
$ mail -a "From: me@...38..."
On my NetBSD system, though, 'mail' does not support -a.
