"No sender canonical map file for outgoing addresses was found in your Postfix configuration. You should either add the appropriate map to Postfix, or disable this feature in Virtualmin's module config page.

I was Checking configurations to make sure things are complete Post-install... I keep butting heads with this issue. I'm brand new to *min products and until recently, I haven't work in Linux servers since 2005 so I'm upside down and backwards. :-(

installed latest Virtualmin (10domain version) on a clean CentOs 7 install. My server is with linode.com and is on a KVM platform +++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++ Issue: "No sender canonical map file for outgoing addresses was found in your Postfix configuration. You should either add the appropriate map to Postfix, or disable this feature in Virtualmin's module config page... your system is not ready for use by Virtualmin." +++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++ I found an older help request in forum from 2008 on this... but Eric's resolution from then didn't help for me so there might be some changes to virtualmin or CentOS 7 that I'm not catching on to... . I tried doing a copy/paste of the config that was recommended from the older article:

[root@jerususalem ~]# sender_canonical_maps = hash:/etc/postfix/canonical

I got the following reply from Bash: -bash: sender_canonical_maps: command not found

Any help would be appreciated. My website has been down for several weeks now because I've been struggling with first Plesk and then Control Panel/WHM config issues. I got tired of uncaring hosts like Hostgator and 1and1 and bluehost allowing my website to sink into the abyss of their lack of customer service. I think that Virtual/webmin will be the platform of choice for several reasons I just need a little help getting things going. I've been watching the videos and reading a lot of doc's and I can't figure out what I'm doing wrong. It looks like there was a resolution at one point but I'm not able to find any newer resolutions for this so I don't know if it's me or something new in CentOS 7 or something new in Virtualmin combined with Centos7 or all the above :-)

Thanks Brad

PS... ***I'll post this in the user forum as well in case any experienced users are monitoring... I'll update my ticket if someone in forum helps first.

Howdy -- hmm, what is the output of this command:

postconf -n

I'll have to pay more attention to tickets. I wasn't expecting such a fast response.

Sorry for the delay, it took me a moment to figure out which feature that was part of :-)

I found it though!

If you look in System Settings -> Virtualmin Config -> Server Settings, there's an option there named "Also update outgoing addresses for mailboxes?"

You would generally want to have that option set to "No" (unless that was recently changed intentionally).

If you set that to No, does the Re-Check Config complete successfully?
