* once all these settings where done, i had to login to the filter via ssh and **manually restart postfix**. otherwise postfix would bind port 25 to 127.0.0.1 only. i guess rebooting the entire filter would fix this issue as well. | * once all these settings where done, i had to login to the filter via ssh and **manually restart postfix**. otherwise postfix would bind port 25 to 127.0.0.1 only. i guess rebooting the entire filter would fix this issue as well. | ||

+ | === Bayesian learning by moving mail to junk folder === | ||
+ | in order for proxmox' | ||
+ | |||
+ | some information i will need to do this: | ||
+ | * the command on PMG to submit a ham or spam to the learning system is < | ||
+ | * a solution on how to use imap sieve filters to trigger a bash script when a mail is moved into a specific folder can be found in the [[https:// | ||
+ | |||
+ | === tag and deliver spam instead of quarantine === | ||
+ | I'm not sure I or my users would be happy with waiting for reports to find out why a recently sent mail did not reach them. after all it's always a good feeling if you can tell someone on the phone that you didn't find their email in your spam folder either, to convince them that they might have had a typo in your email address :) .. | ||
+ | |||
+ | i've started this already. First you need to make sure that spam is no longer quarantined but instead marked and forwarded. | ||
+ | |||
+ | in the PMG web interface click on '' | ||
+ | |||
+ | now on to your postfix mail server.. we need to add a global sieve rule to dovecot that will move spam into a spam folder.. edit ''/ | ||
+ | sieve_after = / | ||
+ | now create the sieve-after directory: | ||
+ | mkdir / | ||
+ | all filters found in this directory will be executed AFTER each user's own filters. so a user can create his own filters to whitelist spam in our case. | ||
+ | < | ||
+ | cat > / | ||
+ | require [" | ||
+ | |||
+ | if header :contains " | ||
+ | | ||
+ | stop; | ||
+ | } | ||
+ | EOF | ||
+ | </ | ||
+ | ** this filter won't compile.. i need to fix this!** | ||
+ | now compile the sieve filter: | ||
+ | sievec / | ||
