We have 2 servers. One with only the iredmail server and one with 2 webshops. CP on the shop server is Webmin. WE have got problem with spammers on the shopserver and therefor now blocked port 25 which they used
Instead we have used an smtp relay service to be able to send order mails etc. But I want to be able to use our own mail server to do it instead. Do I need to change some configutation to be able to do that.
