In fact procmail doesn't even pay attention to the To: header unless
you tell it to, and [re]direct delivery accordingly. The intended
(envelope) recipient is determined during the smtp conversation between
the two mail servers before procmail ever gets the message at your end.
There is absolutely no guarantee that that envelope recipient matches
the To:, Cc: or any other header in the message. For example, my mail
server adds an X-Envelope-To: header thanks to tips gathered here. But
I still get mail from some lists where that header is not added and the
recipient is not indicated *anywhere* in *any* header. It happens when
there are multiple recipients at my site. In your case, however, you
are simply mistaken as to whom the first message was addressed.

^^^^^^^^^^^^^^^^^^^
That is the envelope recipient - the user the remote server told your
server to deliver the message to, and on whose behalf your server
accepted and passed it on to procmail. You can see the same thing in the
next 2 headers.

| The mail was sent to To: <anders(_dot_)nilsson(_at_)seaside(_dot_)se> which
maps to user
| sea0350b but it was delivered to user nilsson on my Linux system (Slackware
| 7.1.0).
No, it was delivered to <nilsson(_at_)seaside(_dot_)se>. The next one was
delivered
to <anders(_dot_)nilsson(_at_)seaside(_dot_)se>.

The to=<nilsson(_at_)seaside(_dot_)se> above indicates the envelope recipient.

| Another mail was delivered correctly (I don't have the headers for this one):
But if you did, the Received: headers would match the snippet from the
sendmail log file below, indicating this message was delivered for
<anders(_dot_)nilsson(_at_)seaside(_dot_)se> - different recipient than the one
above.

Again, to=<anders(_dot_)nilsson(_at_)seaside(_dot_)se> indicates the envelope
recipient
and it is not the same as the first message.
