Our users have reported some emails have not been delivered and others have falsely been tagged as spam.
Our email provider reports AVG Email Scanning may be the cause.
AVG Support says -

Thank you for contacting AVG.

To troubleshoot the emails it is best to turn off AVG email scanning to see if you then receive your emails and they do not get flagged as SPAM. If after turning AVG email scanning off and the problem persist it may not be an issue with AVG. If the problem does persist 

Have others dealt with this possible problem with AVG Email Scanning?
