hoststat, purgestat --
list the status of the last mail transaction with all remote hosts
The hoststat utility causes
to print its persistent host status, enabled with the sendmail
HostStatusDirectory option. Internally, sendmail
maintains status information about network hosts. For example, it stores
whether a host is reachable, or is refusing connections. The
HostStatusDirectory option tells sendmail that it
should save this information externally, and also specifies the
directory where that information will be stored on disk. If
sendmail has multiple children processes running, this option
may be used to ensure that the children have access to this pool of host
The output from hoststat is a table in the following format:
hostname how_long_ago results
The table will contain one row for each host that has its status saved.
The table columns contain the following:
The purgestat utility causes sendmail to purge all
the host-status information saved under the directory specified by
the HostStatusDirectory option. This prevents new
sendmail processes from loading it, but does not prevent
existing processes from using the status information that they
The name of the host that was connected to, which may be an MX
record. A hostname prefixed with an asterisk indicates that
the status file is locked and currently being updated.
Shows how long ago this status record was updated, printed in the form
DD+HH:MM:SS, where DD
is the number of days, HH is hours, MM is minutes
and SS is seconds. If the time of last update was less than
one day ago, the DD+ is not printed.
Shows the results of the last connection attempt, failure, or success.
If no result was stored,
No status available is printed. If
a result was stored, the SMTP reply code, and the text of
the message generated by the other side are displayed.
The sendmail configuration file where the
HostStatusDirectory option is set is /etc/sendmail.cf.
hoststat is a synonym for the -bh command line
switch for sendmail, while purgestat is a synonym
for the -bH command-line switch.
