'vrfy' is a tool to verify email addresses and mailing lists.
|
|
|
|
|
In its simplest form it takes an address "user@domain", figures
|
|
|
|
|
out the MX hosts for "domain", and issues the SMTP command VRFY
|
|
|
|
|
at the primary MX host (optionally all), or at "domain" itself
|
|
|
|
|
if no MX hosts exist. Without "domain" it goes to "localhost".
|
|
|
|
|
More complex capabilities are: recursively expanding forward
|
|
|
|
|
files or mailing lists, and detecting mail forwarding loops.
|
|
|
|
|
Full-blown RFC822 address specifications are understood.
|
|
|
|
|
Syntax checking can be carried out either locally or remotely.
|
|
|
|
|
Various options are provided to exploit alternative protocol
|
|
|
|
|
suites if necessary, and to print many forms of verbose output.
|
|
|
|
|
Obvious limitations exist, but on average it works pretty well.
|
|
|
|
|
Needless to say you need internet (nameserver and SMTP) access.
