Sometimes it may happen that the ZLA module is blocking messages by mistake. If such an 'overblocking' occurs you may help yourself by adding the necessary sender or recipient addresses to a special block- and allow list.
1. use 'vi' to open and edit the block- and allow list for the ZLA module
2. add the addresses to be excluded from the ZLA check to [from_allow] or [to_allow] section of the file
3. restart the mailsec daemon
service mailsecd restart
Note: this block and allow list is for the ZLA module only. It won't help anything if there are overblockings that are caused by other checks on the SMTP level (Dynamic Host Reputation, DNSBL, etc.) or by checks on the Policy level (Spam Signatures, Spam Heuristics, etc.).
