MXScan Configuration Question

Post by Sid » Fri Nov 07, 2008 4:00 pm

I have a question in regards to configuring MXScan. I am wondering what would be the best way to ignore/not scan mail sent from my domain to users in the same domain. I can create the from whitelist, but anyone spoofing my domain will make it through and whitelisting the to address would allow everything. I could use by IP, but we have users all over and they pop before smtp. Any suggestions?

Thanks

All internal emails within the same server is not scanned by MxScan. The logic behind this is because the emails are authenthicated and are coming from a known source they are not processed by MxScan. This also helps to keep things running optimally and puts a lesser load.

Sid, if they outgoing through the same MAILENABLE server as the outgoing SMTP server it will not be processed by MxScan for the same domain.

Assuming that you are using a current version of MailEnable, The only exception is if the emails are sent through an alternative/3rd party mail server/relay/isp mail server.

I have an example of a message sent from a user on the system to a list that was scanned and marked as spam-low. I will send you the logs in a PM.

Thanks,
Sid

Are you sending these to a Mailing List? I can confirm that when sent to regular non mailing list users (individual users), the messages would not be scanned as they would not go into the SMTP Inbound queue.

ps: From the logs you posted it indicates that you are currently using the Professional version. If thats the case, can you please submit your questions using the instructions available at http://www.mxuptime.com/support.aspx

The email was sent to a mailing list, but I also saw a message sent from a co-worker to me that was marked as spam-low. I am using enterprise version. I will go ahead and open a ticket with the above link.

Thanks,

Well I found the issue... I migrated from our old mail server and always had users POP before sending. Well with Mailenable it appears POP before sending fails a good percentage of the time (causing relay denied bounces). I am not sure why it works sometimes and then fails others, but to fix the issue I now have users log on to the SMTP server before sending. Messages no longer get scanned and marked as SPAM.

Thanks for all the help with this issue!

Thanks,
Sid
