Topic: installing DRWEB

======== Required information ====
- iRedMail version (check /etc/iredmail-release): 0.9.7
- Linux/BSD distribution name and version: CENTOS 7.0

- Web server (Apache or Nginx): APACHE
- Manage mail accounts with iRedAdmin-Pro? no

installed DRWEB. everything works, but when the queue of letters the two letters can be connected (the subject of one and the body another). Someone tell me what is wrong in the settings, POSTFIX

Re: installing DRWEB

Excuse me, what's the issue? Any related error message?

Re: installing DRWEB

Errors in the logs no. The problem is that with these settings if you receive multiple messages, then two messages can be combined into one. Will theme one, and the message body from the other. So I do not understand why this could be. If I completely disable amavis in main.cf prescribe

milter_default_action=tempfail
milter_protocol=6
Everything is working correctly. So I think that's right, I was prescribed settings when enabled amavis or is it a mistake DRWEB?

Re: installing DRWEB

Default iRedMail setting doesn't use any milter.

I don't know what DRWEB requires and how it works, so it's better contact DRWEB for tech support.
