Roundcube not working with Postfix when IPv6 is disabled.

[deltatech]

I have had to disable IPv6 in my postfix because messages for servers running IPv6 would only attempt to send to the IPv6 addresses and my network does not support IPv6 yet. So I made the following change to my main.cf

inet_protocols = ipv4 ( it was all )

This worked until trying to send a message via RoundCube. Now we see this...

Aug 4 18:00:04 echo postfix/smtpd[7856]: fatal: cannot handle socket type AF_INET6 with "inet_protocols = ipv4"

does anyone have any idea why Roundcube would require IPv6 to be enabled?

Hi deltatech,

depending on your system configuration of your operating system, you should disable ipv6 support ( systemctl.conf for Ubuntu/Debian ) , rather then trying to modify settings in roundcube and/or postfix. When you did that, then you should run bootstrapper repair, so that Plesk may change possible ipv6 support - settings for your dns / web and mail system on his own, based on your system configuration.
