Exploder archives

The first entry in every AIPS++ exploder list is an email alias which is used to archive a copy of the mail. These aliases have names of the form *-log, where the asterisk corresponds to the exploder name. For example, aips2-workers.list contains aips2-workers-log.

The -log aliases are defined in /etc/aliases on aips2.nrao.edu so that the received mail is piped to a utility, aipsmail (p), which does the archiving using the publically available MH (message handler) system. For example, the entry for the aips2-workers exploder is

   aips2-workers-log: "| /export/aips++/master/etc/aipsmail aips2-workers"

The MH folders reside in directories of the same name as the exploder in the Mail directory beneath aips2adm's home directory. For example the aips2-workers archive resides in

   /export/aips++/Mail/aips2-workers

MH stores each email in a separate file in this directory and gives them numerical names corresponding to the sequence number of the message.

Mail which is more than 14 days old is deleted from the aips2-inhale exploder every evening by an aips2adm cron job running on aips2.nrao.edu.
