prevent Mail from checking for mail if VPN is down My employer insists on using a VPN when people access email via Exchange. Is there any way to prevent Mail from checking for mail if the VPN is down?
Have your employer block access to the IMAP server from non VPN connections. That way Mail can check all it likes but it won't get anywhere. As long as Mail is using a secure connection for the IMAP server it will reject most any nefarious attempt to hijack the attempted connection.
