So if I am currently running Mail Gateway 6.4-4 and I do Configuration-Backup Now and download that file. Install on new VM with https://www.proxmox.com/en/downloads/item/proxmox-mail-gateway-7-0-iso-installer on the same IP address as old machine and upload the configuration from Mail Gateway...

Any idea why I am not seeing any AWL score on some of the messages? Example OK AWL: X-SPAM-LEVEL: Spam detection results: 0 AWL -0.701 Adjusted score from AWL reputation of From: address HTML_MESSAGE 0.001 HTML included in message KAM_DMARC_STATUS...

The default clamav signatures are abysmal and as many other users I have been searching for an alternative. Thank you to @fgams for mentioning this. I have done the changes as noted by @hata_ph and it seems that it's working. If I see any better detection will push this up to management so we...

Hello, Our configuration is one proxmox mail server gateway for receiving email and one for sending email. Is it possible to configure the receiving email server to use sending email server for system messages for example everything that is delivered from Mail Delivery System...

Please keep in mind that if you block like this you are also going to block legitimate email. Not everyone is using mailchimp or similar for just marketing email they could also use it for other services so for example password recovery might not work for some websites as people will not receive...

I see absolutely no reason to use all of those DNSBL blocklists. You will run into multiple problems doing this. Having more is usually not the right way to go. Simple and cleaner setup is better than complex setup. Some problems you will get with running such a high number of DNSBL blocklists...

Just want to let you know that I have upgraded our proxmox mail gateway to latest version and tried to upload the certificate via gui and lost gui connection to the server (error in browser PR_END_OF_FILE_ERROR same as noted here...

Mail filtering is way more complex then just setting up something initially and then forgetting about it. Bad actors will constantly try to pass the spam filter and you will have do constantly adapt and make changes to improve the detection rate. It also highly depends on how much mail traffic...

Just look into the manual https://pmg.proxmox.com/pmg-docs/pmg-admin-guide.pdf Make sure you have the appropriate certificates assigned to your mail gateway (page 33-38) Also make sure TLS is enabled (page 47-48). You should be all set if this is done.

@hata_ph & @Stoiko Ivanov Thank you very much! This seems reasonable and will test on our systems and let you know the results and how I managed to set it up but need some time to do the testing. I was also looking in the documentation that it's possible to scan inside the archived attachments...

Hello, Anyone has an advice how to do this in the most simple way possible. I would like to make a mail filter rule that will remove all attachments except the ones I allow. This is a much better policy then the one that is defined by default. Example on this mail filter rule I would allow...

@tom No offense but this is just unacceptable and not scalable in any way and a waste of man power and a GDPR nightmare at best. We cannot just "check" emails that might contain highly sensitive information for the clients we are filtering mail for and .doc files and similar Microsoft files are...

EDIT: I will try to do the steps on other thread later. Will let you know. I have tested uploading of the certificate via GUI a few times with the same results. It will not upload the full certificate + chain only the first part of the certificate (the wildcard certificate *.example.com). All...

Hello, When trying to add Global whitelist exclusion Add -> E-Mail exception I get this error I am trying to add email address: name.surname+caf_=surname=example.com@gmail.com This is how emails that are forwarded by gmail to some address look like. They have this weird format with + and =...

Hello, Just done the upgrade to Mail Gateway 6.4-4. I am looking in the logs for errors and I am noticing this error. Apr 27 17:12:07 freshclam[814]: WARNING: Ignoring deprecated option SafeBrowsing at /etc/clamav/freshclam.conf:18 I am thinking this is referencing to this option: Will it be...

I have done the upgrade to Mail Gateway 6.4-4 and the error is still present. Are you sure it was added or I am doing something wrong? I would like to change my certificates properly but I can't. There are no clear instructions how to add certificate properly via command line or in what format...

Hello, We have a wildcard certificate for our domain. I want to change it and every time I try to upload the certificate I get this error: I have tried adding or removing parts of certificate chain without any success. The certificate chain works fine on our linux webserver or ftp server. I...

Hello, Running Mail Gateway 6.4-3 with all updates installed. I am wondering if it's possible to force installation of updates.spamassassin.org as soon as possible automatically. I have been checking and it seems every time I check they are not installed. If I install them manually it works...

Just upgraded to latest version Mail Gateway 6.4-3 and hoped this would be fixed but looks like it's not. No matter what message I check there is always BAYES_00(-1.9). How to check if it's operating properly? This value should be variable depending on the message. If you check on...
