Hi Alex, ISA SP1 is postponed due to problems with the SMTP filter. Disable the SMTP filter or desinstall SP1 and all should be fine.

There is one domain "Terra" that send message to us. Only "terra.com.br" receives the following error: "[mail.mydomain.com] said:500 5.3.3 Unrecognized command" SMTP filter has default configuration. Any idea ?
