|Subject:||Mail::Utils::maildomain can't handle $m|
At our site the mail domain is defined as DM$m, where $m is taken from gethostbyname and not the sendmail config. For our config maildomain() returns $m. If maildomain pulls a domain with a $ out of the config file it should fall back to the network checks instead of returning an illegal domain name. I attached a one line patch.
