From: Curtis J Blank <curt@curtronics.com> Date: Wed, 26 Jun 2024 14:14:37 -0500 I think I found the problem. The reported error: "amavis[]: Insecure directory in $ENV{PATH} while running with -T switch at /usr/lib/perl5/5.38.2/Net/Domain.pm line 173." is totally bogus and has nothing to do with the problem. Indeed, the fact that Net::Domain uses domainname at all is bogus, since domainname returns the NIS domain, which has nothing to do with Internet domains. Net::Domain seems to work fine on my system without that code, and without hostname set to a FQDN (and without the /etc/resolv.conf hack I mentioned yesterday), so I may propose this as a fix to the maintainer. (Not that any such fix would be released soon enough to do you any good.) It appears the hostname has to be a FQDN. Having hostname set to the host name and domainame set to the domain name is not adequate. Not necessarily . . . When hostname is a FQDN amavisd starts without error. The same config with the hostname *not* being FQDN on my current postfix email server using amavisd also is and has been running that way since at least 2014 if not 2011. The key is how Net::Domain constructs the FQDN, since Net::Domain has several ways of finding the domain name and tacking it onto a bare hostname. Besides that /etc/resolv.conf hack, it looks at what gethostbyname returns for local host names to see if any of those have domains, and uses the LOCALDOMAIN and DOMAIN environment variables as a last resort. In short, you have other options beyond changing hostname. -- Bob
