Is mailscan or the built in one better or are they similar for spam filtering?

We now have an appliance at the gateway filtering viruses etc. ]]>Thu, 08 Dec 2011 11:31:18 GMT<![CDATA[Spam Filter bug or by design?]]>http://discuss.pscs.co.uk/showtopic.php?tid/15304http://discuss.pscs.co.uk/showtopic.php?tid/15304 I now get a report email each day, but as I am overseas I am using webmail to review my emails. The problem is the link to review the 'spam' is using my internal network IP address to access the email. Therefore I can not see it.
Is this a bug? or by design? or do I have a setting incorrect?

Thanks for any advice.

For the last four days, I've found the following error message in my mailbox:
  • Quote:
VPOP3 has been unable to successfully download an spam filter script update in the last 450 minutes. It has tried 2 times within that time.
The last error received was:
400 (Error Connecting to Site - 11002)


Also, there have been no notices of successful update. From this, it seems that my spam filter scripts haven't been updated in almost a week.

Is this likely to be DNS issues at my end, and if so can you give me name of the host from which VPOP3 would download updates so that I can use nslookup to help troubleshoot?

TIA,

Geoff ]]>Wed, 26 Oct 2011 09:14:06 GMT<![CDATA[dnswl.org - False Reports]]>http://discuss.pscs.co.uk/showtopic.php?tid/15297http://discuss.pscs.co.uk/showtopic.php?tid/15297

We have what this think may be legacy spam filter issue left over from a previous version of VPOP3 we upgrade from. We been living with it up till now but are now in a situation where we need to fix it.

In a previous version of VPOP3 we were running (sorry I forget which version) the spam filter worked in such a way that it would filter all spam to a specified mailbox/user, we called this user 'spambox'.

We then upgrade to our current version (VPOP3 Enterprise Version 4.0.0c build 2570) and the spam filter works differently now, with each user having their own quarantine facility.

However some spam is still being filtered to the now non-existent 'spambox' account and we can nolonger find a setting for this which is why we suspect it may be something leftover from before we upgrade and can onlonger configure it in the current GUI.
It also no longer follows the spam rules, so a whitelisted address will be let thought the new spamfilter but may still be picked up by the legacy setting and filtered to the now non-existent 'spambox' account.

Thanks in advance for any assistance with this issue.

e.g.

"Feedback request from"

would be allowed through, irrespective if it had content that *may* appear spam?

(contact details with a bitmap and disclaimer)

Some users report that this forwarding does not work, this may be why.

I will send an email to them all to try to ensure they delete this footnote, or preferably use the web based tools.

Could Vpop be given an two examples of each users footer (Text and HTML) so it can use this as a mask on any forwarded emails. ]]>Wed, 07 Apr 2010 07:44:34 GMT<![CDATA[Spamfilter error]]>http://discuss.pscs.co.uk/showtopic.php?tid/15099http://discuss.pscs.co.uk/showtopic.php?tid/15099

Emails from recipients that are on VPOP3's whitelist are being wrongly identified as Spam and quarantined as VPOP3 doesn't appear to be looking at our whitelist.

Looking at the message headers I can't find an entry for the whitelist like there is in the example below. The other Spam scores seem fine e.g. blacklist

X-VPOP3-SpamBayes: 0
X-VPOP3-Spam: -680 - SuspiciousHTML(20) whitelist(-700)
X-VPOP3-Spam2: added bayes ham
X-EsetId: E2F5842561963630B8B5

I have tried replacing the whitelist.txt file from as backup copy a month ago, but the problem is still there. I may try and reinstall VPOP3 and see if that solves the problem.

Any advice or help greatly appreciated as having so many legitimate emails identified as spam is annoying.

Thanks
