Folks,

I have two different machines running Postfix on Ubuntu Server 6.06 LTS.
Both of them are exhibiting the same oddness. When the initial word of a
line in the message body of an email is From followed by a space the
line is given a > to comment it out. A lower case from doesn't do it. A
From: doesn't do it. Only From followed by a space. Received doesn't do
it either. It appears to be specific to From.

I know this looks like an MUA issue, but it is definitely a Postfix
issue, since a direct telnet to port 25 and manually inputting the
message will produce the effect, as well as sending a message through
most any MUA. This happens with the default install of Postfix as
packaged by Ubuntu.

To recap, the following message:

From: here to there
>From my house to yours
from your house to mine
>From the other place.

Becomes:

From: here to there
>From my house to yours
from your house to mine
>From the other place.

Does anyone know this problem? Or can you at least tell me where to
start troubleshooting it? I am not a wizard with MTA's in general or
Postfix in particular, but really could use at least a little advice
about where to start on this, because I am fairly stumped.

Thanks.

John Withers
