I am well aware of this, and this is exactly what I wanted to point out. |

Peter's email was either sent to both of the following |
| 14 |
|
| 15 |
smarthost03a.mail.zen.net.uk [212.23.1.20] |
| 16 |
smarthost03d.mail.zen.net.uk [212.23.1.23] |
| 17 |

in short succession or magically duplicated. Just save both messages and |
| 19 |
run 'diff' to verify this. The other MUA-generated headers appear to be |
| 20 |
identical, including "Message-ID: <1722168.phgiPb26BP@peak>". While it |
| 21 |
is possible that zen.net.uk screwed up, I consider it more likely that |
| 22 |
the message was sent twice, as more of their customers would notice a |
| 23 |
systemic problem and probably be quite vocal about it. There's nothing |
| 24 |
to be done if the smarthosts are actually stupid hosts anyway. ;-) |

Does NeoMutt perhaps suppress dupes based on message ID? Thunderbird |
| 29 |
obviously does not. |
