May I know which version of Mac OS are you running and the version of AVG app? Collect OS version by following this article: https://support.apple.com/en-us/HT201260

I had the same problem with Avira, the support was never able to understand why.
Now as soon as AVG included the soon-to-be-released email filter, I get the same problem.
IMAP Emails are appearing as mixed, 2 emails, seems the header is gone.
2 emails content in one single window.
These affected emails are sent to my own domain name (host planethoster.net), seems that gmail are not affected.
what's going on???

Hello,
Always the latest, macOS 10.13.3 (17D47) and AVG also.
I had to desintall it, no matter if mac and/or web security were on or off, emails were 'cut'
The guy from Avira was 'Martin Tuma', it was in early june 2016.
I made him an email account on my domain, could not figure out why that bug.
I can make one for you or send you my avg/mac log.
I have nothing special/gadgets/extensions/utilities on apple mail or mac.
The only thing might be that the mac and the router are very secured, firewall in highest mode, port filtering/blocking, stealth mode… Everything that can be blocked/secured/hidden is set.
Only ~ these ports are opened 21,25,53,80,443,993,465.
Specifically blocked 22,23,123,587,631,992,995
Router in IP4 only, upnp off, pptp, ipsec off…
Several dozen IP or domains are blocked in IP4 and IP6 in etc/hosts file
0 abc.com
::1 abc.com
usual google, facebook, analytics, ads, stats, trackers, few spammers…
