Hi community!
For the last two or three months I was getting issues logging to MIAB imap from my home network. The situation was getting worse and worse. Nowadays it is practically impossible to log. I’ve been doing some research and I found out that the problem is connected to Fail2ban. There are several blocked IP addresses which are all mine (I do use VPN a lot).
I am persistenly logged to 6 mail accounts on several devices via different mail clients (Outlook, Outlook iOS, Mail.app etc). My banned IPs are in the “Chain f2b-dovecot” (what explains Z-Push is working) and “Chain f2b-recidive”.
I really don’t know how are my IPs getting to fail2ban and I’d like to ask for a solution. Should I edit settings for fail2ban manually? How? Will I have to edit it after every update of MIAB?
My MIAB is current version and fully updated.
