Log all mails and content (sSMTP)

  • 772

How can I log all emails going through sSMTP?

I can point my applications to a wrapper script, I just don't know how to write a wrapper script which logs headers and contents to a file (as much information as possible).

Thanks! :-)

    sSMTP has debug logging built in. In your ssmtp.conf file, include the following line: Debug=YES

    When debug logging is active, the entire contents of emails sent via sSMTP, including headers, is logged to syslog.

  2. The following should work as an sSMTP wrapper script. It logs the parameters it is called with and the data provided on stdin. Change the logfile location and name of the real sSMTP as appropriate.

    #!/bin/sh
set -e
LOGFILE="/tmp/ssmtp-$(date +%Y%m%d-%H%M%S-$$)"
echo "$0 $@" > "$LOGFILE"
tee -a "$LOGFILE" | ssmtp.real "$@"

    Remember to make the script executable:

    chmod +x /path/to/script

  3. My working solution is: ssmtp -d9 <email-recipient>.

  4. Why don't you just have your SMTP server log all of the messages received, hence capture the entire message?

    If you use an external server you could just setup a simple internal server that then relays to the external server.
