Running Windows server with MailEnable Standard Version1 - and I need to block 1 IP address - as they are trying to create email accounts.

Where do I block an IP at global level?

You might want to also block them at the firewall level

Current stuff - does that mean they are actually sending mail out through server?

blacklisting will only stop mail delivery.  You should block them at your perimteter (firewall) to stop connections from 189.109.40.26 altogether.

Glad I could help!

Be aware that the IP could be a bsuiness or school, and this have many users behind it.  Either way, it will help you narrow down a pesky user and it will help you take action accordingly.
