What setting could possibly block an IP address just for using an email client?
Posted: 27 Feb 2020, 09:19
An end user is using an email client (like Thunderbird) and are able to receive/send emails just fine, but then after a while, their IP address gets blocked by CSF. The entry for the block in csf.deny is like this:
The end user is insisting they have the correct login details and its proven by the fact that they are able to receive/send emails initially.
Anybody know what CSF setting could possibly be related to this issue?
Code: Select all
