Hi, I was wondering if anybody has come across this particular problem and can’t seem to find the reason, it may be something very silly that I’m missing but I thought I’d ask the question anyway.
I recently installed the system on a VPS in the cloud everything seems to work perfectly however when I set up a mailbox on a domain, I can access it only from the web GUI, for some reason when I put the credentials in for the connection for the mailbox into any mail, client fail2ban automatically blocks the IP address and it seems to alter between two programs, witches postfix and dovecot, I have tried deleting the user mailbox and resetting it up, checking the credentials 700 times are more and I continue to get the same outcome. Checked all DNS records. Everything seems perfect.
I also make sure that any mail client was properly configured, but when trying to connect to the mailbox the IP address is automatically banned in one of the two of the following dovecot or postfix
I have made sure that the IP has been white-listed in the system also, but for some reason, it continues with the same process of alternating between dovecot and postfix when trying to connect from any type of mail client.
Is this a common rookie set-up mistake or is there something else here at play that I’m overlooking?
