It's supposed to be EHLO followed by the full hostname of their server (eg mail.evron.co.il) or IP address (eg [212.179.34.114]) instead of localhost.localdomain. Fixing it should just be a simple change in their mail server's config - right now that config file is calling their server localhost.localdomain, when it should be a real hostname. Alternatively you could whitelist their server in mta_clients_bw.map or remove that check from helo_hostnames.map, but personally I'd ask them to fix their system first. Cheers, Evan
