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.
