[Mailman-Users] iso-8859-8-i messages goes to the shunt directory

[lkolchin at univ.haifa.ac.il]

Hello All,
 
I have the following of problem:
 
When message sent to the list in Hebrew Language in iso-8859-8-i encoding, it doesn't sent and goes directly to /var/lib/mailman/qfiles/shunt,
so I have to run /usr/lib/mailman/bin/unshunt manually to release these messages. 
But then these messages released, the subject line of these messages is empty.
 
Here are some headers of these kind of messages:
 
Content-Type: text/html;
 charset="iso-8859-8-i"
Content-Transfer-Encoding: quoted-printable
Subject: =?iso-8859-8-i?B?Rnc6IPf46eDkIODn+OXw5CDs8OXx8untIOz08Okg5OTu+ODkIA==?=
 
 
On the other hand, messages with windows-1255 encoding arrive to the recipients with no problem.
 
Here are some headers of these kind of messages:
 
Content-Type: text/html;
 charset="windows-1255"
Content-Transfer-Encoding: quoted-printable
Subject: [Academic] =?windows-1255?b?+OD5ICDu8vjqIPr3+eX4+iAg5PHh+OQg5ePl?=
 =?windows-1255?b?4fjl+g==?=
 
 
What's the problem here and how can I solve it?

 
Best Regards,
Leon Kolchinsky
