# Medusa Parallel Network Login Auditor :: SMTP-VRFY

JoMo-Kun / jmk "AT" foofus "DOT" net

The SMTP-VRFY module can be used to enumerate which accounts are valid on a mail server. The module sends the following:
`EHLO some_name
VRFY account@domain
`

The module expects the accounts to be checked to be supplied via the user options (-u/-U/-C). The domain should be supplied as if it were a password. The value sent via the EHLO command can be set using the `-m EHLO:` module option. The default is to send MEDUSA.

This module was written while testing a single mis-configured SMTP SPAM filter. Other devices probably behave differently. Some tweaking of the module may be required.
