Hello,
The VM that is currently runnign iRedMail has 32GB ram and 8 cores. The webserver has it's own valid SSL wildcard certificate.
Although this configuration, if an email transaction occurs, the webclient fails to respond. The nginx webserver is fine, but it isn't delivering content at all, not even static. System load drops to a nearly 0.28% and stays there.

I just launched this and noticed it. At the moment I have 3 domains and a total of 17 accounts.

Bottom line: if I receive an email or send one, the webclient is down. If i try to connect thunderbird, it dies. If i connect gmail, it dies.

Some extra info:

# grep 'max_servers' /etc/amavis/conf.d/50-user
$max_servers = 4;
# grep 'smtp-amavis' /etc/postfix/master.cf
#  -o content_filter=smtp-amavis:[127.0.0.1]:10026
smtp-amavis unix -  -   -   -   4  smtp

Some ideas? Thanks!
