Log mails send with php's mail() function

log_php_mails.md

1. Create a folder to store the script and the mail logs.

mkdir /somewhere/phpmail
mkdir /somewhere/phpmail/mails

2. Place the logmail.sh script in the phpmail folder
3. Make sure the php process has write access to this folder:

chmod -R 777 /somewhere/phpmail

4. Open the php.ini config file and edit the sendmail_path parameter:

On archlinux: /etc/php/php.ini

sendmail_path = "/somewhere/phpmail/logmail.sh"

5. If running php via webserver, you have to restart the webserver.

logmail.sh

#!/bin/bash

UUID=`uuidgen`
UUID=${UUID:0:5}

CURRENTDATE=`date +"%Y-%m-%d %T"`
CURRENTFOLDER=`dirname "$(realpath $0)"`
MAILPATH="$CURRENTFOLDER/mails/mail $CURRENTDATE $UUID.eml"
echo Save mail to $MAILPATH
cat > "$MAILPATH"

#Delete all files in /mails folder that are older than 1 day (-mtime +1)
find "$CURRENTFOLDER/mails/" -mindepth 1 -mtime +1 -delete
