Disable Connection Cache for local filters
in [Postfix]
|
From: Harakiri on 19 May 2010 07:01 Does the following http://www.postfix.org/CONNECTION_CACHE_README.html apply to : When postfix sents a RSET smtp command, and delivers a new mail using the same connection ? I understand that by default it will use smtp_connection_cache_on_demand on a high queue (what number exactly?). However, i would like to disable this for local filters (anti/spam/virus) because sometimes they may get confused and do not support this behaviour. It should still be active when sending to the next hop. Thanks

This is an example from http://www.postfix.org/FILTER_README.html, with an extra command-line option to turn off connection caching for the content filter. /etc/postfix/master.cf: # ============================================================= # service type private unpriv chroot wakeup maxproc command # (yes) (yes) (yes) (never) (100) # ============================================================= scan unix - - n - 10 smtp -o smtp_send_xforward_command=yes -o disable_mime_output_conversion=yes -o smtp_generic_maps= -o smtp_connection_cache_on_demand=no > It should still be active when sending to the next hop. Or perhaps use a not-so-buggy content filter. Wietse

I tested it with -o smtp_connection_cache_on_demand=no but its still reusing the connection. Im using that line on the external SMTPD entry with the -o content_filter= option. > > Wietse >

Im using that line on the external SMTPD entry with the - >-o content_filter= option. Now FOLLOW THE INSTRUCTIONS and put "o smtp_connection_cache_on_demand=no" on the SMTP CLIENT. Wietse
