After you successfully imported all Hestia mail domains into your Proxmox Mail Gateway, you might want to sync Hestia to PMG when you add OR delete a mail domain in Hestia as an allowed Relay Domain mail destination on your Proxmox Mail Gateway. Here’s the how-to!

Make sure your Hestia server can establish a trusted SSH connection to the PMG server, using private keys. You can find plenty of guides on how to do so.

On the Hestia server, create the hooks folder and the add domain script:

mkdir /usr/local/hestia/data/hooks/
cd /usr/local/hestia/data/hooks/

vi v-add-mail-domain-after

Enter:

#!/bin/bash
ssh pmg pmgsh create /config/domains --domain "$2" --comment "$1_`date "+%Y-%m-%d"`"

Save and exit vi. This will connect to your PMG server and create the mail domain with the username and creation date in the comment.

Create the delete domain script:

vi v-delete-mail-domain-after

Enter:

#!/bin/bash
ssh pmg pmgsh delete /config/domains/$1

Save and exit vi. This will execute the command and delete the mail domain on the PMG server.

Make the scripts executable:

chmod +x *

Now you need to modify the v-add-mail-domain and v-delete-mail-domain Hestia scripts to execute the hooks.

vi /usr/local/hestia/bin/v-add-mail-domain-after

At the end of the file, before the exit entry, add this:

# Adding new domain to Proxmox Proxy List
/usr/local/hestia/data/hooks/v-add-mail-domain-after $user $domain
$BIN/v-log-action "$user" "Info" "Mail" "Mail relay entry on Proxmox added (Domain: $domain)."

Save and exit vi. This will execute the previously created hook and adds an entry into the user’s log file.

Now for the v-delete-mail-domain command:

vi /usr/local/hestia/bin/v-delete-mail-domain-after

At the end of the file, before the exit entry, add this:

# Delete mail domain from Proxmox Proxy list
sh /usr/local/hestia/data/hooks/v-delete-mail-domain-after $domain
$BIN/v-log-action "$user" "Info" "Mail" "Mail relay entry on Proxmox deleted (Domain: $domain)."

Save and exit vi.

That’s it! Now add your new mail domain and it’ll show up on your Proxmox Mail Gateway. Or delete it 🙂

See my blogpost about using PMG with Hestia. This is a quick and dirty script to get all Hestia mail domain names for all Hestia users into the Mail Proxy Relay Domains list.

First, on Hestia, export all configured mail domains for all user:

for user in $(v-list-users | awk '{print $1}')
do 
 v-list-mail-domains $user | awk '{print $1}' | grep -v -e 'USER' -e 'DOMAIN' -e '------' -e 'Error:' >> relay_domains.txt
done

Get the relay_domains.txt file to your Proxmox master or node server and run the import:

while IFS= read -r domain 
do
 pmgsh create /config/domains --domain $domain
 echo "Added relay domain: $domain" 
done < relay_domains.txt

Done.

Now you can continue with setting up the mail domains settings as described here.
