SMTP server username and password are readable in database/xml export:
This can possible security leak e.g. when you sent support request, where you send database export to support. Anonymizer does not remove these values.
Username and password should be encoded format in database.
Thank you for reporting this.
Please vote for the linked issue for improving how the username and passwords are stored.
I have changed the summary of this issue and we will use it to track the work on making sure the anonymiser blanks out these values.
Thanks again,
Anton
