Troubleshooting

---

The AntiSpam folder does not appear for my host.

Anti-spam features are only available for hosts with IP addresses. Therefore, you will not see an AntiSpam folder for hosts without IP addresses.

Spam is not being redirected to the mailbox entered in the "Forward To" field.

By default, spam is sent to a mailbox called "bulk" for the "root" account. Note that this is a sub-mailbox, which did not previously exist on your system. If the host has the Sub-mailbox Creation option set to Bounce or Send to Inbox, then the spam will be redirected. See also, "Additional Host Settings".

My Max Mailbox size has been exceeded.

If you chose to forward spam to a mailbox, and receive a large quantity of spam, it is quite possible that the max mailbox size defined for the host has been exceeded. To remedy this, either delete some of the spam from the mailbox, or increase the max mailbox size. To ensure that you are kept aware of this situation in the future, you may want to set up a Full Mailbox Notify Address, so that you will receive an e-mail when the mailbox is near capacity. See also, "Additional Host Settings".

I am still getting Spam in my Inbox.

It is not possible for IMail Server to eliminate all spam. It is inevitable that a small percentage will still get through to your mailbox. However, you can adjust the Advanced Statistical Filtering options to increase the performance of the anti-spam engine. See also, "Advanced Statistical Filtering".

There are no Black lists available for the host.

If there are no black lists displayed on the Add DNS Black List dialog box, then no black lists are enabled at the server level. See also, "Configuring a DNS Black List for the Server".

Anti-Spam is running extremely slowly.

If you have enabled any of the validation tests, this could cause a slowdown. See "Connection Filtering" for more information on the validation options.

Spam is not being sent to the correct mailbox.

Make sure that the mailbox you want spam sent to is entered in the Forward To field on the Content Filtering tab. If the correct mailbox is displayed, check to see if the host or user has an inbound delivery rule that may be sending the message to a different mailbox.

Legitimate e-mail is being identified as spam.

There are several reasons why a legitimate message may be identified as spam. First, make sure that the IP address is not listed in a black list. Do this by examining the message header for the X-IMAIL-SPAM: header. Second, see if the message failed any validation tests. Sometimes, even legitimate SMTP servers have wrong DNS records. If the message is identified as spam by content filtering, you need to use the antispamseeder.exe utility to alter the antispam-table.txt file.

Some of my users cannot send outgoing mail.

You can do two things to assure that your users mail is delivered. First, you can enter your mail server's domain name into the White List. You can also make sure that the Content Filtering for Authenticated Users option on the Content Filtering tab is not selected. Note that the second option should only be used if you trust all of your users not to send spam.

I have setup a "Spam" mailbox for each user to which all messages identified as spam are sent to. But some of my users do not have this mailbox. Why?

The "spam" sub-mailbox is not created until the user account receives spam. So, it is possible that the account has not received any spam. If the users are POP3 users, they will not see the "spam" mailbox unless they log in using the format userid-spam.
