# Mail::Milter::Module::HeloUnqualified(3pm)

milter to check for an unqualified HELO name

## NAME

Mail::Milter::Module::HeloUnqualified - milter to check for an unqualified HELO name

## SYNOPSIS

```
    use Mail::Milter::Module::HeloUnqualified;
    my $milter = new Mail::Milter::Module::HeloUnqualified([EXCEPT]);
    my $milter2 = &HeloUnqualified([EXCEPT]); # convenience
```

## DESCRIPTION

This milter module rejects any domain name that HELOs without a dot, and which is not an IPv4/IPv6 literal.  Whether or not the HELO value corresponds to the connecting host is not checked by this module.

If the EXCEPT argument is supplied, it should be a regex enclosed in a string which will be exempted from this check.  Commonly, '^localhost' is excepted.
