 Posted: Wed Jan 18, 2012 1:59 pm Post subject: [SOLVED PARTIALLY] amavisd-new mimedefang and postfix |
 |
|
Can amavisd-new do what mimedefang can (such as remove an attachment from the email, save the file to an HTTP directory and modify the e-mail so it displays a URL to the attachment instead of the attachment)?
If so, any quick guide or hints?
If not, what's the simplest way to use 2 content filters, first amavisd-new and then mimedefang, within postfix?
Thanks,
Vieri

I don't know mimedefang, but you chose where/which port amavisd-new should forward the message to after scanning - so I'd expect it could simply hand off the message to mimedefang?
Alternatively you could do something like:
| Code: | main.cf
content_filter = smtp:127.0.0.1:20024
master.cf
localhost:20025 inet n - n - - smtpd -o content_filter=smtp:127.0.0.1:10026
127.0.0.1:10027 inet n - n - - smtpd
-o content_filter=
-o smtpd_delay_reject=no
-o smtpd_client_restrictions=permit_mynetworks,reject
-o smtpd_helo_restrictions= -o smtpd_sender_restrictions=
-o smtpd_recipient_restrictions=permit_mynetworks,reject
-o smtpd_data_restrictions=reject_unauth_pipelining
-o smtpd_end_of_data_restrictions=
-o smtpd_restriction_classes=
-o mynetworks=127.0.0.0/8
-o smtpd_error_sleep_time=0
-o smtpd_soft_error_limit=1001
-o smtpd_hard_error_limit=1000
-o smtpd_client_connection_count_limit=0
-o smtpd_client_connection_rate_limit=0
-o receive_override_options=no_header_body_checks,no_unknown_recipient_checks,no_milters
-o local_header_rewrite_clients=
|
To first have postfix send the message to the contentfilter at 20024 - the first filter send it back to postfix at port 20025 and postfix then sends it to the filter at port 10026 which return the message at port 10027
Edit:
On further reading it seems that mimedefang is a Sendmail milter - which you can use like this:
| Code: | main.cf
smtpd_milters = inet:localhost:10025
milter_default_action = accept
milter_protocol = 3
|
Assuming you have mimedefang running - listening on port 10025.
You can have multiple milters like this:
| Code: | main.cf
smtpd_milters = inet:localhost:9999 inet:localhost:8026

Thanks
I'm using mimedefang with postfix and it seems to be working great.
I think I can do just about everything I need with mimedefang; I don't seem to require amavisd. |
