How is Date header supposed to be added?

vixie-cron and mailx seem to expect the local MTA/MSA to add the Date: header 
to outgoing mail, as sendmail and ssmtp do.  Is there a way to get msmtp to do 
so, or a best practice I am missing here?

Currently msmtp does not do this; it assumes that either the user agent
or the MTA at the SMTP server does it (or that it is ok to not have
a Date header).

A wrapper script should work:
----------
#!/bin/sh
formail -b -f -a "Date: `date -R`" | msmtp "$ <at> "
----------

Re: How is Date header supposed to be added?

Thanks for the response.  But is it possible to get cron to use this without 
custom-compiling it?  I understand that it's not your responsibility to 
compensate for the shortcomings of other programs, but I was hoping to find a 
solution that Just Works, since I admin multiple boxes.  But I need to be able 
to override the sending address, so ssmtp won't work for me either.

The easiest way is to use the wrapper script around msmtp that I
suggested: no need to custom-compile anything, you just copy a one-line
script to your boxes.

Building this directly into msmtp would be a little more work, since
msmtp currently assumes that it must never alter the contents of a
mail. Therefore, it has no idea about the mail structure, and in
particular it does not know which headers are already present.

I'm afraid I'm still missing something here.  How do I get the wrapper between 
cron and msmtp?  Any changes I make to symlinks or files that cron or msmtp use 
will be overridden by package managers at upgrade-time.

Hi Joshua!

How do you currently make your cron call msmtp? If you can change a
configuration file, there should be no problem. If your system
has to install msmtp as /usr/sbin/sendmail or similar to make cron
use it, then it depends on your package manager how to avoid overrides
of local changes. I'm afraid I cannot help with that.

it's the MUA that is expected to add the header, and some MTA's add it 
if they receive mail without them. Courier, for example, has the 
possibility to generate the Date: (along with the Message-Id:) header, 
if it is told to (e.g. for local users).

Note that msmtp is designed to do the message submission, not creation.
but you can use Martin Lambers' wrapper if you need.
However I would advise to use mailx or mutt to send the mail.
