in reply to Re^6: use Email::Valid offline
in thread use Email::Valid offline

According to the source code, Line 41 is run when the module is loading (at the use Email::Valid;), so I think this has nothing to do with your call to Email::Valid->address(), and I think no option you change there will influence the line-41 delay and timeout. You can prove this by commenting out the address call, and see if the problem is still there

If the problem persists, I would want to tell Email::Valid to not try the Net::DNS::Resolver, but instead just automatically default to $Email::Valid::DNS_resolver='nslookup', like it does when the Net::DNS module isn't found. But there might be a way to trick it into not: maybe give it a fake Net::DNS already loaded, and then override with $Email::Valid::DNS_resolver='nslookup'? I'm not sure how that might work; it would take some experimenting.
