Hello,

I encounter this message and I don't understand why : I am sending a newsletter once in a week with a perl program I wrote. The body of a mail is stored in a database and any (past) mail can be resent. I use the MIME::Lite library to send the mail (via sendmail).

For the first time in months, I am suddenly getting this 534 error on ONE particular message. If I send a previous message, everything is fine. Sending the "error" message to one account is rejected so it "must" be a header size problem. But it looks so small (quoting Sam) :

There are several fixed limits: a maximum size of 5000 characters per line, and 100,000 bytes maximum total size of all headers.

This is the header of a "good" message :

Content-Transfer-Encoding: binary Content-Type: multipart/related; boundary="_----------=_119730970449260" MIME-Version: 1.0 X-Mailer: MIME::Lite 3.01 (F2.74; B3.07; Q3.07) Date: Mon, 10 Dec 2007 19:01:44 +0100 From: xxxxxx xxxxxx - Editions xxxxmusic <xxxx@xxxxmusic.com> To: ca@yyyyyyyyyy.org Subject: You could be par Torngat - Le bonheur est dans le mail # 31 Message-ID: <cour@neko.thefreecat.org>

This is a multi-part message in MIME format.

This is the header of the "error" one :

Content-Transfer-Encoding: binary Content-Type: multipart/related; boundary="_----------=_119731063469590" MIME-Version: 1.0 X-Mailer: MIME::Lite 3.01 (F2.74; B3.07; Q3.07) Date: Mon, 10 Dec 2007 19:17:14 +0100 From: xxxxxx xxxxxx - Editions xxxxmusic <xxxx@xxxxmusic.com> To: ca@yyyyyyyyyy.org Subject: La raie o milieu par Minimatic (Boutique Chic) - Le bonheur est dans le
mail # 32

This is a multi-part message in MIME format.

This last header was taken from a call to $mail->print(\*STDERR); And the reason for the missing Message-ID

As you see, the headers are nearly the same. I tried using the "good" title on the "error" message with no change.

What can I do to find out what is wrong ?

I am using courier-mta 0.53.3-5 from Debian.

Thanks for your help,
