Very valid point.

Roberto

Good day Roberto.
Is it possible to include updated filter order in the help file?  It's very hard to find in support forum, it's take alot of time to find it when I look for.


Many thanks

Roberto,
 
I actually came up with one issue which also happened with sending to Yahoo and I am not sure there is any real answer.  Gammadyne, (a semi-mass mailer), totally chokes when it hits any grey-listing server including SpamFilter and Yahoo.  I have contacted their Tech Support on this problem and have not yet heard back.  It also happens when I stupidly forget to add the Gammadyne server (on our network) to the donothoneypot list and the IP get's put in the BlackList Cache.  It seems that the SMTP engine just doesn't want to disconnect and kill it's own thread it it gets a disconnect it was not expecting.  This is NOT a SpamFilter issue.  Just thought I would warn folks if they use direct SMTP mailers to send notices to their internal users.

That is correct. Please do note that the greylist will only delay the reception of the first email ever sent by a specific server. Once that email has been received (because the remote SMTP server has retried sending it), the IP will always be allowed to pass the greylist filter in the future.

If really necessary (but there has not been a need for anyone to do this yet...), you can manually add IPs to the greylist files in the \SpamFilter\domains\GreyListAllowed.txt file (which requires stopping/restarting SpamFilter for it to be reloaded).]]> Tue, 08 Jan 2008 16:00:22 +0000 https://www.logsat.com/spamfilter/forums/forum_posts.asp?TID=5171&PID=11469&title=updated-filter-order#11469 <![CDATA[Updated Filter order : Does that mean that we can&#039;t...]]> https://www.logsat.com/spamfilter/forums/forum_posts.asp?TID=5171&PID=11467&title=updated-filter-order#11467 Author: dcook

Does that mean that we can't whitelist a sender to avoid the greylist?
 
I have a client that is not getting some mails and if the client is rejected by the greylist it appears whitelisting will not help?

OK, so i would have to add each email address separately in the "Unfiltered emails" list with a :tag option, then it would work. I could write a script to do that. Do you think performance could be an issue with this workaround?]]> Sat, 24 Feb 2007 06:09:16 +0000 https://www.logsat.com/spamfilter/forums/forum_posts.asp?TID=5171&PID=9793&title=updated-filter-order#9793 <![CDATA[Updated Filter order : Sorry Mike.

Sorry Mike. As the list states, the "Unfiltered emails" has a higher priority than the "not in Authorized TO". Thus as soon as the email is whitelisted, all other tests are skipped (except the antivirus one).]]> Fri, 23 Feb 2007 22:24:38 +0000 https://www.logsat.com/spamfilter/forums/forum_posts.asp?TID=5171&PID=9792&title=updated-filter-order#9792 <![CDATA[Updated Filter order : Read the list, but am still unsure...]]> https://www.logsat.com/spamfilter/forums/forum_posts.asp?TID=5171&PID=9789&title=updated-filter-order#9789 Author: mikek

Read the list, but am still unsure in my case:

I'm trying to take some load off my main smtp server and want to route domains through spamfilter although the customer does not want any spam filtering (yes, those still exist...)

Anyway, I'm using the "Authorized TO EMails" List, which is generated by script off the main mail server. Now I was thinking about adding those domains which do not want spamfiltering to the "Unfiltered Emails" (with :tag), but as I found out until now, then the "Authorized TO EMails" does not get checked and all emails get forwarded to the main smtp server, not only those with valid EMail addresses (which would be my goal - filter out viruses and invalid email addresses on the spamfilter server and forward everything else).

Any possibility to achieve this?

Regards,

Mike
