Hello Billal,

May I ask what do you mean by "making an improvement in the more popular Proxmox". Are you talking about the "Proxmox Mail Gateway" ?

If yes, there should be no issue to put it in front of SmarterMail as an incoming mail gateway. I have a test environnement with PMG in front of SmarterMail and it works like a charm with a bit of configuration tweaks.

Still, PMG, which is a great product but it mainly use Spamassassin as its spam checking engine which is kinda slow compared to Rspamd.

Rspamd is really worth to give a try and is also highly customizable if you learn a bit LUA.

Kind regards.

Hello Sebastien,

Yes I am talking about PNG . I am currently using Barracuda in front of smartermail. I want to remove it now because the costs are increasing. I don't want to add an Email Security Gateway in front of Smartermail. Because I think it should handle customer spam management processes without using a separate panel for Black or white list.

I guess I need to fiddle with Rspamd a little more.

Hi. I used PMG for about a year before finally giving up.

While it worked great for most of the time, it started to show some issues as I migrated more users from my previous antispam server to PMG (I believe it was filtering around 500 or 600 user accounts when I stopped using it).

While PMG had plenty of free CPU, RAM and disk space, it eventually freeze, sometimes lost cluster synchronization, etc.
