That's now been fixed on 5207R, 5208R and 5209R. I also had to update the AV-SPAM, as a certain handler will run (if the AV-SPAM is installed) that messes with the home directory of users on suspend/unsuspend. That also wasn't applying the correct permissions when a user was getting suspended. Both updates are now available via YUM for all relevant platforms. -- With best regards Michael Stauber ___ Blueonyx mailing list Blueonyx@mail.blueonyx.it http://mail.blueonyx.it/mailman/listinfo/blueonyx

Not sure if this is similar ... but offering it: Interestingly, this is also going in reverse with mailman. I've noticed it a lot in the past couple of months. When there are a few bad addresses, combined with huge delays at aspam.google.com (and a few similar places), mailman seems to get "hung up" and eventually has too many files sitting in mqueue (something over 140) which ends up sending two to five copies of the original posts to everyone. The only thing I notice, is that mailman has stopped sending any bounce notices, so bad addresses can be eliminated. No options on the mailman GUI have been touched during the time period. ___ Blueonyx mailing list Blueonyx@mail.blueonyx.it http://mail.blueonyx.it/mailman/listinfo/blueonyx

Hi Meaulnes, It would be a good idea to add the IP of the sending hosts that you've got problems with to that list. It appears that host is not re-queuing emails within a reasonable time if the delivery had been refused with a tempfail. We have had to stop using greylisting unfortunately because a lot of the big players (Microsoft, Google etc.) are using pools of servers and when mail retries it comes from a different server in the pool (and different IP as a result) each time and sometimes it can take several hours before mail finally gets accepted. It is a shame because greylisting does cut down a lot on the spam, but customers started complaining!

Greylisting is - and always has been - a server wide option. You can find the checkbox to enable/disable it unter "Network Services" / "AV-SPAM" in the "Services" tab, where it's named "Milter-Greylist". In the "Networking" tab on that page you can configure the greylist delay, how long it whitelists and you can also manually add IPs or networks to the whitelisted senders, which will no longer be blocked by Greylisting. It would be a good idea to add the IP of the sending hosts that you've got problems with to that list. It appears that host is not re-queuing emails within a reasonable time if the delivery had been refused with a tempfail. -- With best regards Michael Stauber ___ Blueonyx mailing list Blueonyx@mail.blueonyx.it http://mail.blueonyx.it/mailman/listinfo/blueonyx
[BlueOnyx:22536] greylist gone ?
hello I have a user who doesn't get an e-mail from a specific sender — latter says, the mail was returned with the comment «Warning: message 1gWGNB-000Ome-Jv delayed 24 hours». I thought the user might be greylisting. But there is no more greylist settings in the GUI anymore or I'm looking at the wrong place... Is greylisting now obsolete? _~_ '¿') `-´ Meaulnes Legler Zurich, Switzerland +41¦0 44 260 16 60 ___ Blueonyx mailing list Blueonyx@mail.blueonyx.it http://mail.blueonyx.it/mailman/listinfo/blueonyx
