This is a how-to reject nested from addresses.

Example

From:<rick@zimbra.comjohn@zimbra.com>

OR

From:<"rick@zimbra.comjohn"@zimbra.com>"

From:"<"rick@zimbra.com.johm"@zimbra.com>"

Add the following to the top 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 = check_sender_access pcre:/opt/zimbra/conf/sender_pcre, 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
