I'm have a problem with CSF over access to emails.

The client IP is in csf.allow but even so the client it is being temporarily blocked only to email access.

In other words, even the client ip being in csf.allow the client is being blocked temporarily.

I try to release the IP again but it does not appear as blocked, it seems to be only a temporary block.

The client accesses the site and webmail normally but can not log in to webmail, POP3 is blocked.

I need help.

This is a bug or exists a configuration in csf for that.

I need help.

At this moment a client can not access their emails but their ip is allow.

This is the message received from server.

That IP is allowed, but it is not possible to login in webmail, smtp or pop.

I believe it's not blocked because of csf (IP match in csf.allow, block may not work) but because of incorrect authentication data (password, protocol, certificate, cipher suite, etc.) Check your auth logs.
