I have a redhat/plesk/qmail with rbl, odeiavir, spamassasin install.
One domain XXX.com has started having problems. There are about 130 email account and only 2 or 3 are experiencing this.
When they send an email they get
"Task 'XXX.copm' - Sending' reported error (0x8000CCC60):'Your outgoing (SMTP-e-mail server has reported an internal error... blah blah blah... The server responded "rblsmtpd: 188.8.131.52 pid 27817: 451 http://www.spamhaus.org/query/bl?ip=184.108.40.206'
This was reported by outlook on their laptop.
Ok - First I checked at spamhaus
220.127.116.11 is listed as a CBL.
The customer is working that issue. It is the IP address for their main business office.
Now my questions are - This is my customer sending out an email. I thought the rblsmtpd primarily checked emails coming TO my customers, not being sent out FROM my customers. Is this correct?
Second: This is only happening on 2 or 3 computers at the customers site. They have about 60 workers at this site. Why only 2 or 3?
