Running and testing sendmail

To run sendmail in its entirety after running mkdev cf, start the sendmail SMTP server daemon using the command in the /etc/rc2.d/P86sendmail script. If you do not start this daemon, sendmail will only deliver outgoing messages that are not queued and incoming messages from UUCP that are not queued.

Test sendmail by creating and sending mail messages with mail(C). There are three sources for information about sendmail processing:

• error messages which sendmail mails to the mail sender if mail is undeliverable

• the logging mechanism; messages are logged through the syslogd(ADM) facility (the location of log files is defined in /etc/syslog.conf) and the logging level is set as an option either in the configuration file or as an argument to sendmail

• debugging levels selected as an argument passed to sendmail
