OK, I've tracked this problem down now.
When I have a 'search' line in my resolv.conf KDE seems to ignore responses to
DNS queries. My search domain is in the form my.search.co.uk.

Here's the output from Ethereal when KMail tries to check my two POP3S accounts,
both at the same host (hence two DNS queries for the same host):

Standard query A mail.mydomain.co.uk
Standard query A mail.mydomain.co.uk
Standard query AAAA mail.mydomain.co.uk
Standard query AAAA mail.mydomain.co.uk
Standard query response <the correct IP>
Standard query response <the correct IP>
Standard query response
Standard query response
Standard query AAAA mail.mydomain.co.uk.my.search.co.uk
Standard query response, No such name
Standard query A mail.mydomain.co.uk
Standard query A mail.mydomain.co.uk
Standard query AAAA mail.mydomain.co.uk
Standard query response <the correct IP>
Standard query response <the correct IP>
Standard query response
Standard query AAAA mail.mydomain.co.uk.my.search.co.uk
Standard query response, No such name
Standard query A mail.mydomain.co.uk.my.search.co.uk
Standard query A mail.mydomain.co.uk.my.search.co.uk
Standard query response, No such name
Standard query response, No such name

At this point, KMail produces two 'unknown host' errors. As you can see, valid
responses containing the correct IP were returned not once but twice, but KMail
ignored them...
If I remove the 'search' line from my resolv.conf, the problems go away
completely. As I mentioned before, this problem affects all KDE apps, not just
KMail.
