Hello,
this is my first post!
just one question, I have managed to move all databases to 'new vps', and all is working receiving and sending email, lastly I want to move the file /etc/amavis/conf.d/50-user,  which has this nformation in it: (I have omitted domain names)
# Add dkim_key here.

@dkim_signature_options_bysender_maps = ({
    # 'd' defaults to a domain of an author/sender address,
    # 's' defaults to whatever selector is offered by a matching key

    # Per-domain dkim key
    #"domain.com"  => { d => "domain.com", a => 'rsa-sha256', ttl => 10*24*3600 },
    # catch-all (one dkim key for all domains)
    '.' => {d => '********.co.uk',
            a => 'rsa-sha256',
            c => 'relaxed/simple',
            ttl => 30*24*3600 },
});

but when I move the actual file itself to the 'new vps' and delete the new vps 50-user file and place the 'old vps'  50-user file in it's place and restart all services:
#systemctl restart dovecot postfix nginx
#sudo systemctl restart amavis
#sudo systemctl reboot
I cannot receive or send email, can you help me please

Kindet Regards

Have you changed permissions of the amavis files you moved? Make sure the permissions are set to amavis:amavis under /etc/amavis. In that directory run ls -la and post output.

Regards

the migration instructions on this site do not have this point in them

Which one are we talking about? I will update it shortly.

Kindest Regards

Is MySQL service running? If not, please restart it.
If it's running, please restart "amavis" service then try again.
Also, check the SQL username and password used in @storage_sql_dsn and @lookup_sql_dsn in /etc/amavis/conf.d/50-user, make sure it's correct.
