Further research: I can work around the problem provided I turn off the internet connection and manually set up the IMAP and SMTP settings. Provided I set the SMTP to mail.crosswire.org I am allowed to put in a security exception and after that, I can change the SMTP address to a different one from crosswire. If I start with a different SMTP, I get the Warning screen with no checkbox. All other servers that I have tried do not give me this problem. I think it has to do with the nature of the security of the crosswire site, and the fact that it is not found in any of the databases. I have tried in vain to get someone who uses the crosswire mail server to test and confirm, so far without success.
