Hi all,
I have a few clients with random errors like this from valid email addresses. The email obviously does not reach their mailbox.
(host sender.com [x.x.x.x] said: 451 Requested action aborted: local error in processing (in reply to MAIL FROM command))
This happens quiet randomly on various clients only. I'm using postscreen plugin but I was getting this same error before installing the plugin when I was using the standard IMCP config.
Here is some of my /etc/postfix/main.cf
# SASL parameters
smtpd_sasl_auth_enable = yes
smtpd_sasl_security_options = noanonymous
broken_sasl_auth_clients = yes
smtpd_sasl_authenticated_header = yes
smtpd_helo_required = yes
smtpd_helo_restrictions = permit_mynetworks,
permit_sasl_authenticated,
reject_invalid_helo_hostname,
reject_non_fqdn_helo_hostname
smtpd_sender_restrictions = reject_non_fqdn_sender,
reject_unknown_sender_domain,
permit_mynetworks,
permit_sasl_authenticated
smtpd_recipient_restrictions = reject_non_fqdn_recipient,
reject_unknown_recipient_domain,
permit_mynetworks,
permit_sasl_authenticated,
reject_unauth_destination,
reject_unlisted_recipient,
permit
smtpd_data_restrictions = reject_multi_recipient_bounce,
reject_unauth_pipelining
Any ideas where this error is coming from?
Thanks,
Rob
