HP-UX

How to delete old Emails from HP UX system?
Thanks

Your post is somewhat vague and warrants a vague response.

In general unix mail successfully received by sendmail on HP-UX is held in named files in directory /var/mail where the filename is the username. It is usually safe to null a mail file with ">mailfilename". Providing that you avoid filenames which are the same as unix usernames it is usually safe to copy a mailfile within /var/mail prior to nulling the original file.

Of you are talking about undelivered mail stuck in directory /var/spool/mailq it becomes more complicated.

After login:
You have Mail !
ELM
"d" for delete (On each mail you want to delete)
"q"
Answer "Delete messages?" with yes
