County Chief Administrative Officer Bill Rayburn told the London (Ontario) Free Press as much as 20 percent of official county e-mails were being returned by spam filters that reject the 'sex' part of the current domain, @county.middlesex.on.ca.

However, that town's chief officer, Wayne Miller said there have been no complaints about its new @essex.ca domain.
