Well ...
I don't think I have to go as far as values of the kernel variables. 8^D
Would not have idea as to where to look.
But I *do* have it directy "from the Exim's mouth", so to speak.
It is in the paniclog:
[code]
IPv6 socket creation failed: Address family not supported by protocol
[/code]
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.
Rolling back the edit to the file got the expected result:
ie: a 30s delay at boot delay and the same panic log message.
I have no reason to doubt what Exim is reporting.

I never said such a thing.
What I have said all along is that Exim was configured to use IPv6 by default.
Posting about the issue here set the record straight, explaining how Exim/Linux
configurations were set.
That said, I'd like to thank all who posted in reply to my queries and end my participation in
this thread.
