Posted by on August 28 2013 05:54 PM

Q: What is the Include extra spam table checkbox for in the Periodic User Reports?

A: This feature is used for the PDF report option and when enabled it provides an extra column listing the messages that were rejected but not placed in the Quarantine.

Q: What is the Delivery Queue? There's nothing in it?

A: If the destination server is unavailable, all email sent to known destination recipients are queued locally on the filtering servers for delivery. Such messages will be displayed here. They'll be automatically rescheduled for delivery but you'll also have an option to attempt forced delivery for messages here.

Q: What is the limit for entries in the White and Blacklists?

A: There are no set limits however Spam Experts says if you have 10,000 entries this will slow down the page loading time a bit. For the CVS uploading option, the file size cannot be larger than 9 MB.

Q: How do I set up white and black lists for just one user instead of domain-level lists?

A: Spam Experts only provides domain level white and black listing. If one user reports troubles receiving mail from a certain address you as the administrator will need to add it to the domain whitelist. If a user wishes to block a specific address or domain they should instead use the filtering options in their email client to direct mail sent from an address or domain to a specific folder, or their trash.

Q: Why are there both Sender and Recipient White and Black lists?

A. The Sender White and Black lists are the lists that the administrator can use to block or accept messages on a domain wide level. The Recipient lists also show up on user level accounts but they're only intended for addresses at the domain you have set up for spam filtering. Use the Recipient Whitelist to essentially bypass filtering for a specific user on your domain. Use Recipient Blacklist to reject all inbound mail for a specific address at your domain.

Q: Can Periodic Domain and User Reports to be sent to more than one address?

A: The Periodic User reports only support one address to send to however you can specify more than one address for the Periodic Domain Reports. You must enter in the email addresses with a comma and no space between them. Example:,

Q: How do I re-set the password for one of my users?

A: You can set a new password for user accounts from the Manage email users link under Webinterface Users from your domain level access. You can also set a user to inactive or delete their account. You can manually create user accounts here as well. This would be handy if you choose not to enable automatic quarantine periodic user reports.

Q: What is the Clear Callout Cache used for?

A: Spam Experts queries the destination mail server when a message is received for an unknown user to determine if that user is valid. It stores this information for a few hours so if you just added a new address on your domain at your mail server you can clear the cache here so that the system doesn't look at it's own list to determine if this new user should be disregarded.

Q: I just received a spam message to my inbox... Why did that happen if it was supposed to be filtered through Spam Experts?

A: There are a few reasons why you may receive a message that seems to be spam:

  • First verify that the domain has the proper MX records pointing to
  • Verify that the message wasn't sent to an alias or forwarding domain that hasn't been set up as an Alias domain in your Spam Experts control panel, and that the domain also has the proper MX record. Mail sent to an email forward address that isn't listed in the Domain Alias section will not be filtered
  • After that it's time to look at the email headers to verify that the email message went through the Spam Experts filters and wasn't delivered directly to your mail server. View the long headers of that email to find the X-Spampanel-Class line. If you do not have any X-Spampanel entries then Spam Experts didn't get to filter that message. If we're providing you with email service contact support to help determine why it may have been sent directly to the mail server and not through your MX record.
  • If you see the X-Spampanel-Class headers and one of them shows 'ham' or 'unsure' it means that it was filtered but Spam Experts couldn't decide if it was spam or not, so it let it through. If you want to actively assist with system training for your domain you can can set an 'Unsure' tag in the Filter Settings of the control panel to report 'Unsure' messages as Spam or Not Spam accordingly.
  • Use one of the Report Spam options to help train the system so you don't get mail like this in the future. Use the control panel Report Spam option or the email Plugin. To use the control panel Report Spam and Report Not Spam functions you must save your email as an .eml file.
  • Alternatively, you can forward as an attachment a spam .eml file to their reporting address of to report spam. 
  • It is also worth noting that newsletters with an Unsubscribe feature that are not on any bad lists from a filtering perspective are not treated as spam by default. The best way to eliminate newsletter type mail is to unsubscribe, set up a rule or filter in your email program for it, or add it to your Sender Blacklist.

Q: How do I access the IMAP quarantine?

A: You can connect to the IMAP functionality of the Quarantine system through your Email client, as long as it supports IMAP accounts. Instructions on configuration of your email client can be found here: Accessing the Spam Experts Quarantine via IMAP
