vespino I’m currently hosting my Kerio Connect on my home network and as an antispam method I use the SMTP server of my domain registrar. Does mailcow support relaying? I can’t seem to find this in the admin.
esackbauer What do you mean exactly with “relaying”? That would imply that your mailcow is allowing to be used to relay mails to external addresses.
MrScreemi no he means to use a smarthost/smtp relay of his domain provider/registrar to send emails. eg. using google mail as email relay: https://support.google.com/a/answer/2956491?hl=en and yes it is possible to use a smarthost/smtp relay with mailcow: https://docs.mailcow.email/manual-guides/Postfix/u_e-postfix-relayhost/#test-a-relayhost
