Amavis want to connect to clamd through ipv6

[svendsen]

Hi guys,

Because of some troubles we chose to disable ipv6 protocol on a client's server.
Everything now runs fine, but we get some connection errors from Amavis. Seems as it still tries to connect to clamd through ipv6 - even though clamd is confirmed (netstat -tan) listening in ip4-mode only.

How can we force Amavis to connect through ipv4? FYI they are running ZCS NE 6.0.1..

Have you tried

su - zimbra
zmamavisdctl stop ; zmamavisdctl start

[svendsen]

Yes, the whole server has been down and up again..

Check clamd.log in /opt/zimbra/log for any error messages.

This reply is way late, but hopefully still useful...

Depending upon your server setup you may hae run into something like a situation I saw on a solaris server. The amavisd code uses a regex to see if a name looks like an ipv4 address but that regex is a little off. I submitted a minor patch to amavis-user mail list to work around this.

Here's the change:
< my($is_inet4) = $is_inet && $socketname=~/^\d+.\d+.\d+.\d+\z/ ? 1 : 0;
> my($is_inet4) = $is_inet && $socketname=~/^\d+\.\d+\.\d+\.\d+/ ? 1 : 0;

And here's a link to my email to the user list:
