Sendmail+Sasl安装手记

花了两天时间，终于安装成功，用OUTLOOK和FOXMAIL能成功收收邮件。

一：安装前准备。

      1、在DNS服务器中设置邮件系统器的A记录、PTR记录、MX记录。确保DNS服务器能正确的解析邮件系统的域名。

      2、安装环境如下：

                              Redhat Enterprise Linux 3 Update 5

                              Kernel:2.4.21-32.EL

                              sendmail-8.12.11-4.RHEL3.1
                              sendmail-cf-8.12.11-4.RHEL3.1
                              sendmail-devel-8.12.11-4.RHEL3.1
                             

                               imap-2002d-11
                               imap-utils-2002d-11
                               imap-devel-2002d-11
                              

                               cyrus-sasl-2.1.15-10
                               cyrus-sasl-plain-2.1.15-10
                               cyrus-sasl-md5-2.1.15-10
                               cyrus-sasl-gssapi-2.1.15-10
                               cyrus-sasl-devel-2.1.15-10

       3、sendmail.mc配置：

                                     TRUST_AUTH_MECH(`EXTERNAL DIGEST-MD5 CRAM-MD5 LOGIN PLAIN')dnl
                                     define(`confAUTH_MECHANISMS', `EXTERNAL GSSAPI DIGEST-MD5 CRAM-MD5 LOGIN PLAIN')dnl
                                     DAEMON_OPTIONS(`Port=smtp,Addr=xxx.xxx.xxx.xxx, Name=MTA')dnl

                                     使用m4重新生成sendmail.cf文件。

                                                  m4 /etc/mail/sendmail.mc >/etc/sendmail.cf

                                     清空access文件，使用makemap重新生成access.db文件。

                                                  makemap hash access.db

        4、运行ntsysv，将ipop3、sendmail、saslauthd 设备成开机运行即可。

                                    

注！

    如果在RHEL4中出现以下问题现状或者在启动sendmail、sm-client这两个服务器长时间停滞不前。

                    mail pop3[2733]: Unable to locate maildrop for USER: Mailbox does not exist

   解决方法：

                     autocreatequota: -1
                 createonpost: yes
