I have a problem with MailWasher saying, "Skipped automatic mail check because the was no Internet connection" when, in fact, the ADSL connection has not been interrupted. This has been happening since I installed the Linksys switch and it shows up in the Sygate log as a blocked UDP response from the IP address of the switch. I can only assume that MailWasher is expecting a response from the mail server which is being blocked by SPF. Apart from allowing all UDP polls to pass through the firewall can anyone suggest a rule that would get over this problem?
