This is a how-to reject nested from addresses.
Example
From:<rick@zimbra.comjohn@zimbra.com>
OR
From:<"rick@zimbra.com john"@zimbra.com>"
From:"<"rick@zimbra.com.johm"@zimbra.com>"
Add the following to the bottom of the /opt/zimbra/conf/zmconfigd/smtpd_sender_restrictions.cf file
check_sender_access pcre:/opt/zimbra/conf/sender_pcre
Next, create the /opt/zimbra/conf/sender_pcre file with the following.
/@.*@/ reject
Restart MTA
zmmtactl restart
Check it.
postconf | grep ^smtpd_sender_restrictions
You should see something similar to to this...
smtpd_sender_restrictions = reject_authenticated_sender_login_mismatch, check_sender_access regexp:/opt/zimbra/common/conf/tag_as_originating.re, permit_mynetworks, permit_sasl_authenticated, permit_tls_clientcerts, check_sender_access regexp:/opt/zimbra/common/conf/tag_as_foreign.re, check_sender_access pcre:/opt/zimbra/conf/sender_pcre
