Proxmox Mail Gateway 5.0 looks great! Good work. During my tests I found a few things I would like to share/ask. I'm using PMG for incoming mail filtering only. I've setup a domains MX record to the PMG and added the domain to "Relay Domains" and setup a Transport to the destination host/mailserver. 1) PMG sees all mail as outgoing. I need all mail filter rules to apply to outgoing instead of incoming. In the statistics I only see traffic and details for outgoing but it really is all incoming email. 2) At Mail proxy Options I set DNSBL Sites, that works but I would also like to add the whitelist "list.dnswl.org" with negative scores like this: zen.spamhaus.org*2 bl.spamcop.net*1 b.barracudacentral.org*1 ix.dnsbl.manitu.net*1 psbl.surriel.com list.dnswl.org=127.0.[0..255].0*-2 list.dnswl.org=127.0.[0..255].1*-3 list.dnswl.org=127.0.[0..255].[2..3]*-4 But the field doesn't allow me to do so: Code: Parameter verification failed. (400) dnsbl_sites: invalid format - value 'list.dnswl.org=127.0.[0..255].0*-2' does not look like a valid dnsbl entry 3) TLS for Mail Proxy is disabled by default. Shouldn't this be enabled by default? 4) Greylisting can be enabled/disabled globally only. I don't want to use it by default because of the delay in incoming emails (only unknown triplet, I know, but still). But I would like to be able to enable it for some domains. When we add a domain to Relay Domains an option to enable greylisting or not would be really nice. 5) We plan on using many domains of different customers. But they need to be able to view there quarantined email/spam. There's a user role Quarantine Manager but that user can see all quarantined email. Is there some generic solution for this? Or should I change the subject of spam messages to mark them as SPAM: and setup rules on the destination server to move those emails to a spam folder?
