Sendmail 8.11.1 Release Notes

5. PidFile
The location of the ProcessId (Pid) file can be defined using this option. The
default setting for this option is:
#O PidFile=/etc/mail/sendmail.pid
/etc/mail/sendmail.pid will be taken as the default file, if this option
is not set. If you choose a directory other than /etc/mail for the pidfile,
please ensure that the directory has proper write permissions as those of
/etc/mail.
6. ProcessTitlePrefix
The prefix string for the process title shown in ‘ps’ listings can be specified
using this option. By default, this option is commented. For example, if you
set this option in the sendmail.cf file as:
#O ProcessTitlePrefix=HPUX_Sendmail-8.11.1
The command ‘ps -ef | grep sendmail | grep -v grep’ might
show ‘sendmail: HPUX_Sendmail-8.11.1: accepting connections’ in the output.
7. TrustedUser
This option can be used to specify a user, who can own important files instead
of root. This option necessitates ‘fchown’. The default setting for this option
is:
#O TrustedUser=root
8. MaxMimeHeaderLength
The size of the MIME headers and parameters within those headers can be
set using this option. This can also be used to protect Mail User Agents (MUA)
from buffer overflow attacks. The default setting for this option is:
#O MaxMimeHeaderLength=10
9. DeadLetterDrop
This option can be used to specify the location of the system-wide dead.letter
file, which was formerly hardcoded to /var/tmp/dead.letter. The default
setting for this option in this version is:
O DeadLetterDrop=/var/tmp/dead.letter
Please note that Sendmail will not save mails anywhere if this option is not
set at all.
