Managing mail queues
2. Select sendmail and click the Configuration tab. Separate configuration
files are maintained for each burb.
3. Select the Aliases file for the burb that is running sendmail and click Edit
File.
To redirect messages to a different user, type the user name after the
colon for the account you want to redirect. For example, if you want to
direct root’s messages to user name piper, you would locate the root
line in the file and edit it to look like this:
root: piper
4. Save the changes you made to file and then close the file.
5. Click the Save icon to save the configuration changes and rebuild the
configuration and database files. This will also automatically restart the
sendmail servers.
6. To deny or restrict certain SMTP connections, add an appropriate proxy
rule.
If a sendmail message cannot be delivered, (for example, if the
destination system is down) messages are temporarily placed in
queues until they can be delivered. There are separate queues for
each server: /var/spool/mqueue.c (local) and /var/spool/mqueue.# for
the Internet and the trusted burbs. You should check the queues
periodically. If there are a lot of messages that are several days old,
you may have a problem with your system or its configuration.
To view the mail queue output type the following command:
/usr/bin/mailq
The output of this command will list the messages currently in the
queue you chose, along with information about each message. Each
message is assigned a unique identification number, which is shown
in the first column.
