.IX Header "DESCRIPTION"
\&\f(CW\*(C`Mail::Verify\*(C'\fR provides a function CheckAddress function for verifying email
addresses.  First the syntax of the email address is checked, then it verifies
that there is at least one valid \s-1MX\s0 server accepting email for the domain.  Using
Net::DNS and IO::Socket a list of \s-1MX\s0 records (or, falling back on a hosts
A record) are checked to make sure at least one \s-1SMTP\s0 server is accepting
connections.
.SH "ERRORS"
.IX Header "ERRORS"
Here are a list of return codes and what they mean:
.IP "0" 4
The email address appears to be valid.
.IP "1" 4
.IX Item "1"
No email address was supplied.
.IP "2" 4
.IX Item "2"
There is a syntaxical error in the email address.
.IP "3" 4
.IX Item "3"
There are no \s-1DNS\s0 entries for the host in question (no \s-1MX\s0 records or A records).
.IP "4" 4
.IX Item "4"
There are no live \s-1SMTP\s0 servers accepting connections for this email address.
