salut à tous,
j'utilise le serveur de mail "Courier Mail server 0.53". Mon probleme est que lorsque des utilisateurs envoient des mail à certaine personnes, il y le message d'erreur suivant:
-Pour certains message en reception:
CORRUPTED MESSAGE

This is the Courier Mail Server 0.53 on mail.monserveur.ci.

I received the following message for delivery to your address. This message
contains several internal formatting errors. This is often caused by
viruses that attempt to infect remote systems. Instead of blocking
this message, I converted it to a safe, text-only attachment that can be
safely read with a text editor.

This sometimes also happens when the sender's mail software has a bug
that creates improperly-formatted messages. Although these kinds of
formatting errors may often be ignored by other mail servers, this
server detects and intercepts improperly-coded messages in order to
prevent viruses from taking advantage of bugs in E-mail programs:

-----------------------------------------------------------------------------
This message contains improperly-formatted binary content, or attachment.
-Pour certains en emission:
The message WAS NOT relayed to:

IMPROPER FOLDED HEADER FIELD MADE UP ENTIRELY OF WHITESPACE

The RFC 2822 standard specifies rules for forming internet messages.
In section '3.2.3. Folding white space and comments' it explicitly
prohibits folding of header fields in such a way that any line of a
folded header field is made up entirely of white-space characters
(control characters SP and HTAB) and nothing else.
je vous avoue que je ne sais pas comment resoudre ce problème!
Merci de bien vouloir me donner un coup de pousse!
Bonne prog à tous.
