[cf.in, 5-opts.pl, config.pm] Subject: [pmg-devel] [PATCH pmg-api/pmg-docs v2] make filter timeout configurable X-BeenThere: pmg-devel@lists.proxmox.com X-Mailman-Version: 2.1.29 Precedence: list List-Id: Proxmox Mail Gateway development discussion List-Unsubscribe: , List-Archive: List-Post: List-Help: List-Subscribe: , X-List-Received-Date: Fri, 12 Jan 2024 19:22:51 -0000 v1->v2: * addressed Thomas' feedback - Thanks very much * changed the setting from filter_timeout to filter-timeout (thus template toolkit needs to access it as 'pmg.mail.item('filter-timeout') * fixed a few glitches in the commit messages original cover-letter for v1: This series improves mail-handling in case pmg-smtp-filter takes too long in processing a mail. Currently the timeout is based on postfix defaults which differ between after-queue filtering (600s) and before-queue filtering (120s) (patch 1/4 unifies the timeout, and is meant as a stop-gap measure). In both cases - once the timeout is reached the behavior is inconvenient (to put it mildly): * postfix detects the timeout and reports a temporary 4xx code to the sender, while pmg-smtp-filter sends the mail further after processing anyways This results in such mails getting delivered multiple times to the recipient (and you need the administrator of the server sending to PMG to remove it from their queue, for the deliveries to stop). Tested by adding a `sleep 200;` in PMG::Utils::analyze_virus_clam. The docs patch is necessary for patch 3/5 (new config-options need to be known in the doc-generator) pmg-api: Stoiko Ivanov (4): templates: postfix: set same timeouts for before and after-queue pmg-smtp-filter: cleanup use of gettimeofday config: postfix: make smtp-filter-timeout configurable pmg-smtp-filter: die if processing took longer than the timeout src/PMG/Config.pm | 9 +++++++++ src/bin/pmg-smtp-filter | 21 ++++++++++++--------- src/templates/main.cf.in | 5 ++++- 3 files changed, 25 insertions(+), 10 deletions(-) pmg-docs: Stoiko Ivanov (1): doc-generator: add new option filter-timeout gen-pmg.conf.5-opts.pl | 1 + 1 file changed, 1 insertion(+) -- 2.39.2
