fetchmail has had problems today. There are a lot of "nameserver failure" messages in maillog. While it was trying to resolve these domains, it clogged up qmail & nothing got in or out for several hours (Serious Problem).
I suspect that the offending domains were in the "To" field of an incoming mail, though I can't find which one it was.
1. Why should fetchmail try to resolve addresses that aren't in my domain?
2. If this happens again, what can I do to make sure I continue to get a mail service?

Hi Rob,
It might be that it is actually resolving domains in the "From" field. You could modify the template for fetchmail (I assume you are using multidrop ?) and add the 'no dns' option to it (sorry I'm typing on the run and can't be more specific at this point).

Thanks, Kelvin. I tried that, but fetchmail failed with a "segmentation fault" (it sent me an e-mail).

Hi Rob,
The only time I get segmentation faults on the SME server I setup is when there's something wrong hardware-wise (most times it's the RAM).

Hmmm...
Well, it's the only segmentation fault I've ever got, and the machine's been running for about a year now. It's ECC RAM, so I would expect to see other indications if this was the case.
fetchmail works perfectly again if I remove the nodns option..
