Hi list, I'm facing an strange problem with amavis. I have a created a rule to block all outgoing attachments from MYNETS, as follow:
$policy_bank{'MYNETS'} = { originating => 1, terminate_dsn_on_notify_success => 0, bypass_banned_checks_maps => [ @local_domains_maps ], banned_filename_maps => ['BLOCKALL'], }; %banned_rules = ( 'BLOCKALL' => new_RE( [ qr'^\.[a-zA-Z0-9]*$' => 1 ] ), 'MYNETS-DEFAULT' => new_RE( [ qr'^\.(rpm|cpio|tar|zip|rar)$' => 0 ], qr'.\.(vbs|pif|scr)$'i, qr'.\.(exe|vbs|pif|scr|bat|cmd|com|cpl)$'i, qr'^\.(exe-ms)$', # banned file(1) types ), 'DEFAULT' => $banned_filename_re, ); All clients are Outlook Express configured to send mail only as plain text. It was working 'till a few hours ago, when all mail sent from internal addresses were blocked: amavis[7743]: (07743-10) Blocked BANNED (text/plain,.asc), MYNETS LOCAL [192.168.0.33] [192.168.0.33] <inter...@addres.com> -> <outgo...@address.com>, quarantine: badh-3qdj59cxln10, banned-3qdj59cxln10, Message-ID: <00b601c9e54b$4cef9f50$2100a...@recepcao1>, mail_id: 3qdj59cxln10, Hits: -0.911, size: 696, 1561 ms So I had to change BLOCKALL to 'BLOCKALL' => new_RE( [ qr'^text/plain$'i => 0], [ qr'^\.[a-zA-Z0-9]*$' => 1 ] ), In order to allow mail to go through again. Anyone can explain why amavis is blocking a plain text e-mail, all of the sudden? No parameter in amavisd.conf where changed, I've checked Outlook Express to make sure that no attachments where included on the message and that it was indeed being sent as plain text. Everything was the same as before, when it was working, but mail gets blocked unless I allow plain/text extensions to go through.
