I have just upgraded to 6.0.7 - so far without any issues.

However, I am in the process of adding back some additional configuration settings I have in amavisd.conf.in

I noticed a new setting in the 6.0.7 shipped file.

@debug_sender_acl = qw( kaos[at]kaostech.com );

[at] modified from @

I am far from an expert in what amavisd does but, from what I can quickly read, this seems to be a sender email address that will trigger some kind of debugging.

Is there any security issue with this being in there ?

Should it be removed ?
