Yeah, I reached out to them and they said they are not having issues. This is happening on every transaction as well. I verified with them that I wasn't blocked or rate limited as well.

I have one DNSBL that always has issues, not sure where the issue lies. Possibly DNS, but I'm not 100% sure. Looking for some ways to troubleshoot to verify the issue. You can see the warnings here for spamrats: Apr 14 17:22:46 smtp postfix/postscreen[3157]: warning: dnsblog reply timeout 10s...

I've replaced the existing one's with these. I'll keep an eye on the logs and see what it looks like and report back if there are any issues. Thank you! :)

Hello, I'm trying to verify that my regex looks good, in theory, it should be fine, but I'm seeing this in the logs: Apr 13 18:18:11 smtp postfix/smtpd[1039]: warning: regexp map /etc/postfix/senderaccess, line 1: Invalid preceding regular expression Apr 13 18:18:11 smtp postfix/smtpd[1039]...

It was easier just to shift+click about 175 blacklist entries and delete them that way in the WebUI. Thank you though.

What is the best way to remove all entries in a users blacklist? I've tried the following: pmgsh delete /quarantine/blacklist/*@*.* -pmail 'user@domain.com' 200 OK But all the addresses still exist in the blacklist. Attempting to delete the user addresses in the WebUI results in for the one with...

It's working great now, it's no longer a honeypot and I'm not having to baby sit the disk space either. Much better! :)

Thank you for your patience and help. Hopefully this thread will help someone else out in the future. :)

It also appears to be working now, as the database has valid entries now as well :) cp -a /var/lib/postfix/verify_cache.db /tmp/test.db postmap -s btree:/tmp/test user1@domain.COM 0:0:1618254626:250 2.1.5 Recipient OK user2@domain.COM 0:0:1618256027:250 2.1.5 Recipient OK...

So yes, I'm sending to a one of the valid domains to an invalid address. So I should remove my domains from: Configuration > Mail Proxy > Whitelist? So I removed the sender and receiver whitelist for the two domains we own and the database is there now: -rw-r--r-- 1 postfix postfix 8192 Apr...

So the two domains that we have run through Proxmox > Exchange. I've sanitized them to a generic domain name, but the syntax matches. /^.+@do-main-2\.com$/ OK /^.+@do-main1\.com$/ OK

I've attached a log with an email that went through to an Unknown user. Thank you! :)

Hi @Stoiko Ivanov! I took a look at this a bit today, finally had some time. Here's what I see when running postconf -d in regards to the address verification database: address_verify_cache_cleanup_interval = 12h address_verify_default_transport = $default_transport...

Thank you!

Getting a ton from *.cam as well... I attempted to add the wildcard to the domain, I'm assuming the best way to match those would be just to use the Regex option? Thanks. :)

Hello, I've been troubleshooting and am getting the following emails that are level 1. Any ideas on tweaking the rules out of the one's listed to block them properly? Thank you in advance! :) Apr 6 13:26:30 smtp postfix/smtpd[6796]: connect from...

Thank you again for the help :) * Postfix and the appliance has been restarted on multiple occasions. * The only IP's I've whitelisted are the exchange server and my printers which are local, on-premise devices. * All incoming email goes exclusively through PMG. The log can be seen in comment...

Thank you :) /etc/postfix/main.cf: # auto-generated by proxmox compatibility_level = 2 command_directory = /usr/sbin daemon_directory = /usr/lib/postfix/sbin data_directory = /var/lib/postfix # appending .domain is the MUA's job. append_dot_mydomain = yes smtpd_banner = $myhostname ESMTP...

I do have a template that I copied from the pmg templates and added the myorigin line so that bounced emails will use my domain, I posted the entire template file below: # auto-generated by proxmox compatibility_level = 2 command_directory = /usr/sbin daemon_directory = /usr/lib/postfix/sbin...
