Hi,

I finally managed to migrate my ~current OpenBSD's sendmail to smtpd. Congratulations \
is the first thing that comes to mind... at least from a configuration perspective, \
smtpd is a lot simpler - and that's an understatement.

Now, for the strange stuff: I've got a pretty straightforward system: smtpd as MTA \
and dovecot as IMAP server. sendmail used to deliver to mbox, as does smtpd. I know \
the benefits of using dovecot to deliver mail, but I haven't bothered to do so as I \
don't have thousands of mails anyway. This is also beside the point of this email.

I also use procmail as my mail post processor which just matches a few rules and \
moves mail to specific mbox's. For a strange reason, every time smtpd delivers to an \
mbox directly, mail would be properly appended to the mbox; however, when procmail is \
on the way (and smtpd logs that it delivers via mda), the From_ line is removed from \
the mail, basically invalidating the mbox format and appending the delivered mail to \
the last mail in the file.

What I'm missing exactly is this line:
From ${sender.email}  Mon Apr 21 17:41:14 2014

where ${sender.email} is the email address of the sender. I had to run procmail with \
"-f -", which basically creates a From_ line if there isn't one or updates the \
timestamp of an existing one. Of course, because the From_ line doesn't exist, \
procmail creates something like: From ${USER} Mon Apr 21 17:41:14 2014

I triple checked that smtpd would create the From_ line when there is no procmail in \
between. I double checked that this happens with the original configuration that \
comes with smtpd.

Am I missing something or can this be a bug?

NB: ~current as of 17 April 2014 or thereabouts - I know that ~current is not \
properly supported but I thought I'd let people know anyway.

Thanks,


Gabriel
