Hello list, I would like to use MimeDefang to sanitize the emails that arrive at one of our 3 mailing lists, i.e., to convert html->text, remove unsafe attachments, and remove+webserve file attachments larger than 500KB.
There are few tutorials on this subject and most, like Mickey Hill's http://www.mickeyhill.com/mimedefang-howto , ask for the installation of sendmail and present a config tightly coupled with sendmail internals (the real sendmail, not postfix's sendmail). Could you please provide (or point to) a couple of working examples on how to setup mimedefang with postfix (would it be better done as a transport+filter, or as milter?) and, if possible, throw some light on the advantages/disadvantages of each alternative? Thank you, Mark PS: My current setup uses postfix 2.9.3 + mlmmj 1.2.18 + ubuntu 12.04, to manage 2 low volume mailing lists (< 300 subscribers and less than 50 emails/month), as follows: MAILING_LIST_1 <mailing_lis...@example.com> MAILING_LIST_2 <mailing_lis...@example.com> postconf -e 'virtual_alias_maps = /etc/postfix/virtual-alias-maps # /etc/postfix/virtual-alias-maps mailing_lis...@example.com mailing_list_1@localhost.mlmmj mailing_lis...@example.com mailing_list_2@localhost.mlmmj postconf -e 'transport_maps = /etc/postfix/virtual-transport' # /etc/postfix/virtual-transport mailing_list_1@localhost.mlmmj mlmmj:mailing_list_1 mailing_list_2@localhost.mlmmj mlmmj:mailing_list_2 # /etc/postfix/master.cf # transport for the mlmmj mailing list manager mlmmj unix - n n - - pipe flags=ORhu user=mlmmj argv=/usr/bin/mlmmj-receive -F -L /var/spool/mlmmj/$nexthop
