not sure if this is related but my mail server started rejecting everything out of desperation i removed this from mail server config
-->>   removed this ',reject_rbl_client bl.spamcop.net'

every out and incoming mail had postfix/smtpd[10318]: NOQUEUE: reject:   blocked using bl.spamcop.net;

smtpd_recipient_restrictions = permit_sasl_authenticated, permit_mynetworks, check_client_access hash:/etc/postfix/sender_whitelist, check_client_access hash:/etc/postfix/sender_blacklist, reject_unauth_destination, reject_non_fqdn_sender, reject_non_fqdn_recipient, reject_unknown_recipient_domain, reject_rbl_client zen.spamhaus.org, reject_rbl_client bl.spamcop.net

after removing this everything works - i am sure it is important - but at least my mail is working again

and of course i checked to see if my mail server was black listed - it is not

spamcop was down, and it should be resolved now
