Hey guys,
I'm having a problem with a client, where CSF catches several disconnected and tls connection closed errors.
The client is able to use the email correctly when adding the IP in whitelist. If it is not on the white list, every time the client uses the email the IP is blocked.
I thought it was a login and password error, but everything is fine and connected, however, IMAP always generates this error in the log below:
Please, does anyone have any idea how to solve this problem?
Thank you =)
