Hi all,
I am new to this forum, but I have been managing zimbra mail server for some time now.
I have this problem that i need help. The mail server i am managing (production server) was doing fine, of recently, attachements within
incoming emails, from external domains are no longer seen in those emails. It is as if they have been removed somehow.
so whenever someone sends email with attachements are delivered successfully, but without attachements.
Please help me to understand and solve this issue. I am using zimbra collaboration network edition 8.8.10

Hello,
maybe a mail system filtering is dropping attachment silently ?

Re: problem receiving incoming email with attachements
after i inspected headers carefully, i came to realise that amavis was throwing " BAD HEADER SECTION, Improper use of control character (char 0Dhex)".

How the Zimbra Support help ?
Re: problem receiving incoming email with attachements
zimbra support edited configuration to pass bad headers
Re: problem receiving incoming email with attachements
open /opt/zimbra/conf/amavisd.conf.in file, added the following line
$allowed_header_tests{‘control’} = 0;
restart the amavis service zmamavisdctl restart
$allowed_header_tests{‘control’} = 0;
restart the amavis service zmamavisdctl restart
