Incorrect filter when using non-English language

When squirrelmail language is set to english, my filters
(procmail) work
well.

When I create a new filter using french language, the
To: From: .... get
translated in the .procmail file.

Of course, these identifiers should *not* be translated.

##Begin Filter Configuration -- Please do not edit by
hand, use SquirrelMail
MAILDIR=$HOME/Maildir/ # Default mail directory

###From '' lcaron '' INBOX.Sent '' m '' on '' off '' ''

* ^From:.*lcaron
$MAILDIR.Sent/

:0:

into the .procmail
>file?
Right

The procmail should remain unmodified (with english
words)
From:
To:
Cc:
