07 Remediation
Upgrade to hMailServer 6.3.7, which masks every line of a SASL exchange and every AUTH initial response in the SMTP log, but the user name of AUTH LOGIN and the authentication identity of AUTH PLAIN, as before. Until then, turn SMTP logging off where it is not needed or keep the logs readable by administrators only, remove the AUTH exchanges from a log before sharing it, and where a log may have been read by others revoke the OAuth 2.0 grants and change the passwords of the accounts that signed in (after upgrading as well: an upgrade does not take credentials out of logs already written, so delete or redact those logs).
