This is the home of chkuser, the patch used with
qmail and
vpopmail in order to check at
SMTP level the existence of recipients, avoiding useless bouncings and saving
bandwith.
For informations and support , see the chkuser 2.0 section.
Previous versions of chkuser, named chkusr, are still available
here.
This
version has some bug fixing and new features, allowing better handling of MySQL
connections and dedicated usage of SMTP port (see RFC 2476 about Submission
port)
Includes
also improved logging, for a better monitoring of SMTP traffic
