Pegasus Mail & Mercury

Hi,  I've recently noticed that some of the Spam emails I'm receiving have the Delivery-Notification-To header set which causes Mercury to send a delivery notification and hence informing somebody (the spammer?) that the email account is active.  As I believe that the it is not mandatory to respond to the Delivery-Notification ...

I noticed a rather serious problem today:   My system's set up to block illegitimate mail.  I demand authentication to relay and I greywall, but today a piece of spam came through with one legitimate address for a local user, and about 12 users on other systems in the CC/BCC fields.  Because one user was legit the message was accepted by ...

I'm trying to come up with a general purpose rule to deal with the 419'ers hiding behind Google mail.  Below are the headers from a typical Google spam: Return-path: <johnbasil005@torba.com>Received: from ag-out-0708.google.com (72.14.246.240) by BKBUSA.COM (Mercury/32 v4.62) with ESMTP ID MG0000AD;   9 Jul 2008 11:03:03 ...

Greylisting won't help you because the spammers can just dump their mail onto your backup MX which will then happily relay it on to you from both a trusted and persistent (genuine) mailer and address.   It's unlikely that a UK ISP would neglect to provide an outgoing smarthost (SMTP/submission) server.  But yes, MercuryE is the module ...

Can't connect to 213.180.114.52 on port 25: Timed out   Firewall?  TCP port 25 incoming needs to be opened.  Check your router.  Check your software firewall configuration.  In the Windows firewall, allow mercury.exe.   Tip: if you only have one mail server, it is easy to do away with a large volume of ...

Greenman:   I don't understand how Mercury was able to accept the mail from 61.145.143.171 when it is outside the allowed range of IP addresses. Am I missing something here? Is there any further configuration I need to carry out to ensure that Mercury only accepts SMTP connections from the allowed ranges?   It's not clear ...

Hi Folks I have a question about SMTP mail from allowed IP ranges. All mail we receive goes through MessageLabs. This means that all email has a banner inserted at the end of the message stating it has been scanned by MessageLabs. Today we received an email which was classified as spam, and which did not include the banner. The MercuryS log ...

I was trying to track down some info on installing SpamHalter on my Mercury/32 machine. http://www.ararat.cz/eng/show.php?spamhalter  has a link to ''Unofficial SpamWall/SpamHalter WIKI pages at: http://email.arcm.com/wiki/index.php/SpamWall  - which is dead. The Google cache of the above page has a link to ...

I vaguely remember reading about a way to filter messages containing the Big5 character set.  At the time it wasn't relevant so I didn't make note of it.  About two months ago I acquired a spammer using Big5 who pops up all over the place from open proxies and I'd like a simple way of dealing with it.  Does anyone have a filtering ...

There is absolutely no necessity to get complicated. The more complicated the solution, the more difficult it is to implement. And few of the ''anti-spam technologies'' tackle the problem where it occurs, which is actually where it must be tackled. Once it gets past the SMTP layer, i.e. at the mail clients, all the ''anti-spam technologies'' are ...
