[Declude.JunkMail] 451 Requested action aborted

[srv]

We are using Smartermail 3.x with Declude 4.x and Message Sniffer running on W2K3 and not using any outgoing mail filters in our Declude config. We are not using Hijack. Late last week, we started getting undeliverable emails to a client (only happens with this client – any emails at their domain) with the following showing up in the returned email:   Could not deliver message to the following recipient(s): Failed Recipient: [EMAIL PROTECTED] Reason: Remote host said: 451 Requested action aborted: local error in processing (message save)   In the SmarterMail log it looks like this:   09:40:46 [05438] RSP: 220 mg2 SMTP; Fri, 01 Sep 2006 09:41:49 -0500 09:40:46 [05438] CMD: EHLO smmail.ourdomain.com 09:40:46 [05438] RSP: 250 mg2 Hello 09:40:46 [05438] CMD: MAIL FROM:<[EMAIL PROTECTED]> 09:40:46 [05438] RSP: 250 <[EMAIL PROTECTED]>...
