Greetings, all. I'm having some problems with a QmailToaster mail server
that despite my best efforts, I can't solve. I would appreciate any help
you can give me.
1. We have one domain where [EMAIL PROTECTED] is receiving mail addressed to
[EMAIL PROTECTED] without being bcc'd, carbon copied, or included as a
recipient.
2. Subscribers to at least three EZMLM mailing lists on two different
domains are getting messages from the EZMLM program letting them know
that some messages to them are bouncing. At least two of the bounced
messages are being returned due to error code 5.5.0/550. All of the
subscribers/recipients are using different email providers.
3. Our users are getting lots of spam.
Steps already taken toward spam reduction:
- We're using SpamAssassin as part of the Simscan-toaster. Filter
training is being done using sa-learn. Spam and ham are sent as
attachments (most of our customers use outlook or outlook express and
this is the most efficient way to get the high volume of spam to us) to
two mailboxes. The mail is then "unattached" and run through sa-learn as
--ham or --spam. Sa-learn is run as the vpopmail user 2 to 4 times per
week, and the spam is learned server-wide. Domain-specific and
user-specific learning is not enabled.
- simscan is set to discard any messages with a spam score higher than
8.
- 3 blacklists have been added to the simscan RBL configuration.
However, despite all of these steps, several of our users have reported
that they are not noticing a reduction in the volume of spam that they
are receiving.
Is there anything else we can do to simplify and/or improve this
process?
