so we have PMG configured to sign all emails with DKIM, and have setup an SPF record and a DMARC record for our outgoing domain. everything works nicely, except... spamreports generated by proxmox. at least, spamreports directed at users that have setup a forward to an external domain...

it seems that both the proxmox-spamassassin (from PMG) and the sa-compile (from stock Debian) provide a /usr/bin/sa-compile file, which prevents the two from being co-installable. is it necessary that proxmox-spamassassin provides that binary (rather than depending on the sa-compile package...

greylisting is great, but mails take considerably longer. one option is to just lower the netmask of greylisted IPs, but since this is a global option it means that while it works for big sender networks and it also defeats greylisting in more fragmented networks. and you still get the initial...

i would like to tighten my rules, so people get less spam :) e.g. if no mail beyond a given threshold has ever been released, i can be pretty confident that I could also just drop those emails, so there's less quarantined emails. (right now, people get a quarantine notification practically each...

i have my quarantine authentication configured to use LDAP or Ticket, and setup an LDAP backend (without groups). When I click on "Users of 'myldap'" in the Configuration/User Management, i can see all the users in a table DN Account Primary Email...

the statistics-page of the webinterface gives me information on INCOMING Total Incoming Mails Junk Mails Greylisted Mails Spam Mails SPF rejects Bounces Virus Mails OUTGOING Total Outgoing Mails Bounces Virus Mails practically the same information is sent in the daily "status reports"...

i do love greylisting, but: is there a way to bypass greylisting for some hosts/networks? the obvious problem is with large providers (outlook, googlemail, gmx,...) that keep resending from different IPs, thus keeping the mail in the greylisting for ages. i know i can whitelist hosts, but...

wir haben ein kleines problem mit einem sender network, wodurch von unser "Community Subscription" PMG installtionen keine emails von dort angenommen werden. der sender ist "editorialmanager.com" (ein publisher für akademische journals), deren outgoing mailserver sind...

i'm running PMG-6.1-3, with before queue spam-filtering enabled. since some time (probably about the same time as i enabled before queue, but i don't really remember), it seems that the mailgateway is unable to send administrative emails any more. PMG is mailgate.example.com, and it's...

since i've enabled the "before queue" filtering, i get notifications of smtp-errors every now and then: the sender/receiver/sending-host tuple looks like totally legit (and includes "trusted" mailserverse; "trusted" in the sense that i trust them to do a good job and not send out spam; but not...

after upgrading to PMG-5.1, my ClamAV installation complains about being outdated. E.g. this is what I get when I manually click the "Update Now" button in the web-frontend: ClamAV update process started at Mon Oct 15 14:55:46 2018 WARNING: Your ClamAV installation is OUTDATED! WARNING: Local...

would it be feasible to train the bayes-database with emails the user released from the quarantine as ham? - sometimes false-positives get caught by the quarantine. - the users will usually notice, and release these mails from the quarantine. - my idea is to use this information to train the...

I would like to allow my users to access the quarantine page from the internet (not just the intranet). "somewhere" I've read, that one shouldn't expose the entire webgui/api to the wild internet, and only restrict access to the actual quarantine. (unfortunately I cannot find that reference any...

i'm having a hard time, doing anything useful with `pmgsh` (besides interacting with the config; which i find easier to either do directly on the filesystem or via the webinterface). esp. i'd like to query the quarantine database (e.g. which receivers have quarantined emails; list basic...

in the tracking center i can filter by sender, receiver, time-span and "filter" (which appears to be some simple text-matcher, without a regex engine). i find that i would also like to filter the results based on the delivery state, e.g. limit the display to entries that are accepted/delivered...

the statistics charts in the web-interface allow me to enable/disable of following categories (inbound): - Incoming Mails - Junk Mails - Virus Mails - Bounces for reasons unknown, i cannot enable/disable a chart for good HAM mails, which is probably just the difference between incoming and...

today i got an error in Sep 11 12:15:17 mailgate pmgpolicy[8138]: *** FATAL PROGRAM ERROR!! Unknown method 'char_str_list' *** which the program has attempted to call for the object: *** list.example.net. 7190 IN TXT \# 11 0a737066322e302f707261 *** *** Net::DNS::RR 1519 has no...

currently, the statistics page allows me to select a given day or a summary for an entire given month. i find this slightly inconvenient when dealing with incidents that happen at night (that is on two consecutive days) or at the turn of the month (e.g. 2018-08-27..2018-09-03). Also, in the...

i cannot connect my PMG to an LDAPS (ldap/ssl) server. the LDAPS server uses a valid certificate (signed by letsencrypt), and I can use it just fine with e.g. ldapsearch -x -H ldaps://ldap.example.com`. however with PMG, the connection is terminated, because of certificate errors. The root...

is it possible to do (slight) customizations of the login-page (without hacking the source)? the problem i'm trying to solve is that the term "User name" is a bit ambiguous. My users can authenticate via the department LDAP (so we allow username/password based login to the quarantine; not just...
