POP3 blacklist?

[Simulcast]

Hi,

We have someone probing our POP3 accounts for weak passwords.

We have failed login lockout enabled and swatch notifying us of the abuse, but it's still problematic.

I searched the forum but didn't see a way to blacklist IPs from access the POP3 service. Is that feasible or something best handled at the firewall if we want to try and implement?

All best.

I would handle that at my firewall level. If I have an idiot like that I don't want that IP anywhere around my network. I would ban than IP at my firewall.

Just my thinking

Thanks Spectra, we did indeed go the firewall route. Cheers.
