Quoting W B Hacker <[email protected]>:
'Typically' on a whole-globe basis, nameservers need as much as
three days before changes have propagated to 'near as dammit' all of
them.
Ordinarily, one sets the TTL's quite short ...
This can't have anything to do with DNS, since my manual telnet
callout test, using the same host name, worked without a hitch when
Exim did not. Besides, the DNS did not have to be changed before or
after Exim was modified.
Cheers,
Jaap
