Virtualmin + Postfix

Virtualmin
1

Hello,

The versions I am using are:
Operating system: CentOS Linux 7.8.2003
Webmin version: 1,954
Usermin version: 1.803
Virtualmin version: 6.11
Postfix: 2.10.1

I am trying to configure Postfix to send and receive emails from a virtual server, however it is not allowing to receive and is not sending emails.

When checking the postfix status, I find the following message:

Aug 04 21:05:33 nsde.smartienda.com postfix / trivial-rewrite [23164]: fatal: open dictionary: expecting “type: name” form instead of “virtual_alias_maps”

The Postfix main.cf configuration is as follows:

Does anyone know what I can do to solve this problem?

This is a syntax error. You’ve mixed up some lines here.

I’m not sure what you’re going for, but virtual_alias_maps is it’s own directive and needs it’s own line.

Hello Joe,
Thanks for answer my question. I just want to configure Postfix and use it to send and receive emails with Virtualmin Servers.

I have removed sender_dependent_default_transport_maps = virtual_alias_maps = hash: / etc / postfix / virtual end restart Postfix service.

Now I can send and receive just local mails but I can´t send or recieve from other domains.

Sending from streamingweb@streamingweb.site to @paginasweb.site I get this message:

This is caused by a security issue?

The email leaves the Virtualmin server (that’s good) but is rejected by the recipient’s server.

Cloudmark thinks your IP address has a poor reputation - I.e. lots of bounced messages / spam from the email which originated from it in the recent past.

Also check if you have proper reverse DNS, SPF and DKIM records in place.
