Sendmail Question

[Steve Holmes]

I notice a strange problem from time to time with my combination of
fetchmail and sendmail.  The default configuration of sendmail rejects
unqualifyable sender addresses.  That's all fine and good but if one
of those messages shows up in a batch of mail being fetched with
fetchmail, It kicks me out with a return code of 10 and I can't
subsequently fetch any of my accumulated mail off the server.  My only
solution thus far is to relax the domain lookup restriction in
sendmail; then I can fetch it all down.  Has anyone else on the list
experienced this problem? If so, have you any solutions?

Thanks for any help.
