body raw_body headers raw_headers request code content_type parent_type charset meta_data is_mime_vendor_specific is_mime_personal |

I needed to block email based on the Subject header. The solution is simple: Edit main.cf as root and uncomment or add:
|
|
header_checks = regexp:/etc/postfix/header_checks |
Next, creaate or edit /etc/postfix/header_checks as root and add the following line:
|
|
/subject:\sbad subject text here/ REJECT header_checks NO SPAM ALLOWED /subject:\stest subject text here/ DISCARD header_checks NO SPAM ALLOWED |

|
|
unzip -d ~ ~/Downloads/AutoRaise-master.zip cd ~/AutoRaise-master && make clean && make make install |
My ~/.AutoRaise file:
|
|
#AutoRaise config file delay=3 |

The aws s3 sync command is slow and painful! I needed a more efficient way to sync to large buckets (prod to dev). Finally settled on RClone: https://rclone.org/docs/
|
|
cd {extracted zip dir} ./rclone config cat ~/.config/rclone/rclone.conf |
During rclone config I called remote “s3” ;-}
|
|
./rclone sync -v --progress --fast-list --checksum s3:wyzaerd-demo-prod s3:wyzaerd-demo-dev |
