IMHO that's not the reason for a 30s delay. > Without any editing of the exim4.conf.template file, I invariably got that > paniclog message: > (yes, I am now aware that this file is a matter for Debian packagers to solve) > > Adding the line disable_ipv6 = true to the the 'Main' section of the > exim4.conf.template file > immediately solved the problem I was having. > > ie: no 30s delay and no panic log message. Yes, this (again IMHO) disables queries for AAAA records. But, repeating myself, I suppose, that a correctly working resolver should respond to such queries immediatly. No matter, if you've IPv6 enabled or not. And Exim, in case it got an IPv6 adress for a host to connect to, should get an immediate "connection refused" or similar error from your host's OS and then retry the other addresses (IPv4 being among them) without any delay. Please provide logs, strace output or tcpdump PCAP files captured during the startup phase of Exim.
