测试 SpamAssassin
要测试 SpamAssassin，请首先在 spamassassion.opt 文件中设置 debug=1。您不必在 imta.cnf 中启用特定于通道的 master_debug 或 slave_debug。然后，将测试邮件发送给测试用户。msg_svr_base/data/log/tcp_local_slave.log* 文件应当具有类似以下内容的行：
15:15:45.44: SpamAssassin callout debugging enabled; config /opt/SUNWmsgsr/config/spamassassin.opt 15:15:45.44: IP address 127.0.0.1 specified 15:15:45.44: Port 2000 selected 15:15:45.44: Mode 0 selected 15:15:45.44: Field "Spam-Test: " selected 15:15:45.44: Verdict "spam" selected 15:15:45.44: Using CHECK rather than SYMBOLS 15:15:45.44: Initializing SpamAssassin message context ... 15:15:51.42: Creating socket to connect to SpamAssassin 15:15:51.42: Binding SpamAssassin socket 15:15:51.42: Connecting to SpamAssassin 15:15:51.42: Sending SpamAssassin announcement 15:15:51.42: Sending SpamAssassin the message 15:15:51.42: Performing SpamAssassin half close 15:15:51.42: Reading SpamAssassin status 15:15:51.67: Status line: SPAMD/1.1 0 EX_OK 15:15:51.67: Reading SpamAssassin result 15:15:51.67: Result line: Spam: False ; 1.3 / 5.0 15:15:51.67: Verdict line: Spam-Test: False ; 1.3 / 5.0 15:15:51.67: Closing connection to SpamAssassin 15:15:51.73: Freeing SpamAssassin message context |
如果日志文件中不包含类似以上内容的行，或者 spamd 未运行，则将最后的句点 (.) 发送到 SMTP 服务器后，SMTP 对话框中将返回以下错误消息。
452 4.4.5 Error writing message temporaries - Temporary scan failure: End message status = -1
此外，如果在 option.dat 中设置了 spamfilter1_optional=1（强烈推荐），则将接受邮件而不会过滤邮件。如同没有启用垃圾邮件过滤功能一样，并且 tcp_local_slave.log* 中将显示以下内容行：
15:35:15.69: Creating socket to connect to SpamAssassin
15:35:15.69: Binding SpamAssassin socket
15:35:15.69: Connecting to SpamAssassin
15:35:15.69: Error connecting socket: Connection refused
15:35:15.72: Freeing SpamAssassin message context
|
在 SMTP 服务器接收到整个邮件之后（即，最后的 "." 发送到 SMTP 服务器之后），在 SMTP 服务器向发件人确认它已接受邮件之前，系统将调用 SpamAssassin。
另一项测试是使用诸如 Mail-SpamAssassin-2.60 目录中的 sample-spam.txt 来发送样例垃圾邮件。此邮件中包含以下特殊的文本字符串：
XJS*C4JDBQADN1.NSBN3*2IDNEN*GTUBE-STANDARD-ANTI-UBE-TEST-EMAIL*C.34X |
对应的 tcp_local_slave.log* 包含类似下面的内容：
16:00:08.15: Creating socket to connect to SpamAssassin 16:00:08.15: Binding SpamAssassin socket 16:00:08.15: Connecting to SpamAssassin 16:00:08.15: Sending SpamAssassin announcement 16:00:08.15: Sending SpamAssassin the message 16:00:08.15: Performing SpamAssassin half close 16:00:08.15: Reading SpamAssassin status 16:00:08.43: Status line: SPAMD/1.1 0 EX_OK 16:00:08.43: Reading SpamAssassin result 16:00:08.43: Result line: Spam: True ; 1002.9 / 5.0 16:00:08.43: Verdict line: Spam-Test: True ; 1002.9 / 5.0 16:00:08.43: Closing connection to SpamAssassin 16:00:08.43: Mode 0 verdict of spam 16:00:08.43: Mode 0 verdict of spam 16:00:08.47: Freeing SpamAssassin message context |
mail.log_current 文件中的对应条目如下所示。请注意目标地址的 +spam 部分，该部分表示将邮件归档到名为 spam 的文件夹中。
