Hi all

I have Dovecot on my Linux-Mint workstation, running IMAP for the Thunderbird client thereon, but previously also for my phone and laptop clients as well. Since upgrading to Linux-Mint 19, however, although the Thunderbird client on the workstation works just fine, the other clients can't connect. I've disabled the firewall, and nmap shows the ports open, so it seems like some setting in the server. Can anyone help?

lsof -i :143 lsof -i :993

What does your mail logging report when the clients try to connect? Anything that blocks connections from outside the dovecot host itself?

Dovecot version is 2.2.33.2 (d6601f4ec)

dovecot -n output:

2.2.33.2 (d6601f4ec): /etc/dovecot/dovecot.conf

Pigeonhole version 0.4.21 (92477967)

OS: Linux 4.15.0-55-generic x86_64 Linux Mint 19.1 Tessa
