    Hey guys,

    We just bought an enterprise licence and im running on from OVH.

    I can't set-up my custom SMTP server, it gives me a timeout error on port 25 and a very long error when i activate SSL:

    MailKit.Net.Smtp.SmtpCommandException: 5.7.1 Mail from 66.70.186.206 has been blocked by Trend Micro Email Reputation Service.

    I went in my openstack server and added the rules for port 25 and 465 on egress but it's not working. I know my SMTP info is correct, its the same on my on premise config and it's working there.

    Anyone have any ideas?

    Yes, contact ovh and explained the situation - your IP is blacklisted. They should be able to give you another one.

    Do you have a fixed IP address ?, if so you will have to update it within 3CX - Settings -> Network Settings

    You may have to access the 3CX via http\\ip:5000 instead of https://fqdn:5002 until you can update the 3CX setttings

    Shared hosting is a pain. Sometimes you can pay extra for a static IP address but many times even that will have scars. Gmail may be the way to go.

    If they issued you a static IP ask them for a clean one and have them check it at mxtoolbox link I put above.
