Dovecot SSL Cert Problem

@aaraya1516 wrote:

I'm trying to loadbalance a few dovecot instances and the SSL cert being shown to the users is the dovecot server's not the HAproxy version. The documentation for this is sparse and scattered, so I couldn't make a perfect setup that gave valid ssl certs. Does each dovecot server need to have a cert with the haproxy domain for this to work?

Here's my config:

global
        log /dev/log    local0
        log /dev/log    local1 notice
        chroot /var/lib/haproxy
        stats socket /run/haproxy/admin.sock mode 660 level admin
        stats timeout 30s
        user haproxy
        group haproxy
        daemon

        # Default SSL material locations
        ca-base /etc/ssl/certs
        crt-base /etc/ssl/private

        # Default ciphers to use on SSL-enabled listening sockets.
        # For more information, see ciphers(1SSL). This list is from:
        #  https://hynek.me/articles/hardening-your-web-servers-ssl-ciphers/
