26.3.10 Server-Side Rules (SSR) Are Not Working

A filter consists of one or more conditional actions to apply to a mail message. Since the filters are stored and evaluated on the server, they are often referred to as server-side rules (SSR).

This section includes information on the following SSR topics:

• 26.3.10.1 Testing Your SSR Rules

• 26.3.10.2 Common Syntax Problems

See also 18.15 To Debug User-level Filters.

26.3.10.1 Testing Your SSR Rules

• To check the MTA’s user filters, use the command:

# imsimta test -rewrite -debug -filter user@domain

In the output, look for the following information:

mmc_open_url called to open ssrf:user@ims-ms
   URL with quotes stripped: ssrd: user@ims-ms
Determined to be a SSRD URL.
   Identifier: user@ims-ms-daemon
Filter successfully obtained.

• In addition, you can add the slave_debug keyword to the tcp_local channel to see how a filter is applied. The results are displayed in the tcp_local_slave.log file. Be sure to add mm_debug=5 in the option.dat file in directory /msg-svr-base/config in order to get sufficient debugging information.

26.3.10.2 Common Syntax Problems

• If there is a syntax problem with the filter, then look for the following message in the tcp_local_slave.log-* file:

  Error parsing filter expression:...

  • If the filter is good, then filter information will be at the end of the output.

  • If the filter is bad, then the following error will be at the end of the output:Address list error -- 4.7.1 Filter syntax error: desdaemona@sesta.com

    Also, if the filter is bad, then the SMTP RCPT TO command will return a temporary error response code:

  RCPT TO: user@domain 452 4.7.1 Filter syntax error
