OK, I am using a Macbook Pro running OS X 10.6.8. My mail server ISP is Virgin Media and I am receiving mail via Mac Mail using IMAP protocol with SSL on. With the Mail Shield on my messages do not come through or are at best intermittent and I do not get any error messages. If I try using Thunderbird, again the messages do not arrive but in the log there are error messages about duplicate serial numbers on certificates. I have tried uninstalling and re-installing Avast but to no avail so I have turned the Mail Shield off again. Please let me know if there is any other information you require that might help in resolving this issue.
