Cannot receive mail if more than 40 recipients in address list

Your best bet is to find out what email address the Supplier uses to send out their mailshots, and then to Whitelist this address in your security settings.  

The Spam filter assigns plus points according to certain traits within the message e.g., free offer, pharmacy, rolex, etc.  A Whitelist entry deducts a large chunk from the total score which, when the filter analyses the score, assures it is properly received.

On the status screen on the right hand side of the Mdaemon screen, select the Security tab, and then the Anti Spam tab above that to see exactly what it is doing with those messages.

Hi,
1.On the "Security" menu,there is "Tarpit" option,open it,and Disable "Active Tarpit",you can try it.
2.You'd better update your Mdaemond mail server to 9.6.3.

Thanks for the replies..
Just an update on this..
Expansion of problem..
The person cannot receive the mail when the sender puts it in the BCC column of outlook . When they put it in the To column or CC column it works fine..

Is there some setting that i can change to allow him to receive when his address is in the BCC Column.
Its just that thats the way his suppliers send out the mail...

Have you tried adding the supplier to the Whitelist?  I am confident this will work, regardless of whether the recipient goes into To or CC or BCC.

If you look through the "All" activity logs, or in real-time, on the Security tab, Anti-Spam tab when one of these mailshots is arriving, you can see exactly how it is "scored".  If it doesn't appear on the "All" tab at all, then there is a different kind of problem you have.

Sorry, meant to say:-

...If it doesn't appear on the "All" activity log at all...

(Am assuming you have ticks in all the relevant logging activity boxes)

Cheers for reply.. What do ya mean as having all ticks in the relevant boxes...

I recommend you choose the:-

Log everything into separate files depending on the date

...option.  People often don't know that they need to trace something until over a week has passed.

In the Options panel, if nobody else is using this pc, tick everything that does not say "performance drain" after it.  The only exception to this rule is the option that says:-

Log sessions in real-time (debug logging - performance drain)

which I find too valuable to not have.  

Uh oh I hate double negatives, let me restate that explicitly:  I recommend that you have Log sessions in real-time ticked, despite the performance drain warning.

Hi,
1.I recommend you update your mdaemond to version 9.6.3.
2.You'd better add you recipients to mail list.
