First I have the Exim paniclog message which gave me a clue as to what could have been
going on.
[code]
IPv6 socket creation failed: Address family not supported by protocol
[/code]
Then I have that adding the line below to the 'Main' section of the exim4.conf.template file
gets rid of both the delay *and* the paniclog message:
[code]
disable_ipv6 = true
[/code]
And lastly I have that I can faithfully reproduce the problem by simply rolling back the edit.
As expected, the rollback brings back both the delay *and* the paniclog message.
