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...

@grefabu would you mind marking this issue as SOLVED?

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...

DoH. i dunno why I haven't enabled SPF in the first place.

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...

alternatively it would be nice if the admin interface had a special login (e.g. "/admin") and the user-login would live under "/" see also https://forum.proxmox.com/threads/make-quarantine-page-publicly-available-in-a-secure-fashion.47215/

yikes. indeed (and with /quarantine login also succeeds) but... how should anybody notice the difference? the two login-screens look identical. iirc, a couple of years ago i have requested some possibility to adjust the login page (mostly to tell people that they have to use their...

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"...

well, the documentation says: and i said: so afaict, the SMTP whitelist does not fit my bill. it seems to be mostly targetted at SMTP hosts that are setup as mail forwarders towards the PMG and which can be "fully trusted" (e.g. because they are under your control).

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...

pinging the support team : @Stoiko Ivanov, @martin ...

the problem seems to be, that spamcop.net used to be a very reliable service and has vanished without warning or announcment into thin air this sunday morning. See the Reddit and WikiPedia articles. The way this was done looks actively hostile (and it took me ages to debug, with many...

@Stoiko Ivanov ich glaube, ich habe jetzt (nachdem ich debugging hochgedreht habe) eine spur, leider noch keine lösung... remote verwendet Microsoft SMTPSVC als outgoing SMTP-server scheinbar bevorzugen MS-SMTP-server BDAT anstelle von DATA PMG/postfix announced CHUNKING (also BDAT-support)...
