D | Indicates the server was found via the DNS lookup of the hostname. If the hostname returns more than one IP address, all of them will be flagged with 'D' and will be used first for INIT requests before falling back to the other servers. |
I | Indicates the server to which the last INIT request was sent. |
F | The server has not responded to requests and is considered to have failed |
T | The server is currently being timed. |
- Create either an IP or email address black/white list. This can be used as a filter either against an email address or an IP address of a potential spamming MTA. To configure the list go to UTM >AntiSpam > IP AddressYou can add words, phrases, wild cards and Perl regular expressions to match content in email messages.
You can go to UTM > AntiSpam > Banned Word
You can also use wild cards and Perl regular expressions to block instances contained in messages, however, Perl regular expression patterns are case sensitive for antispam banned words.
To make a word or phrase case insensitive, use the regular expression /i. For example, /bad language/i will block all instances of bad language regardless of case.
Wildcard patterns are not case sensitive.
