Just take a look; they are plaintext !!

$ less /var/spool/mail/jrm

shows the content. You can travel up and down easily.

If you wanted, you could

$ mv /var/spool/mail/jrm /var/spool/mail/jrm_save

Then

$ ls -l | mail -s "test and new mail" jrm

should create a new spooler file for jrm:

$ ls -l /var/spool/mail/jrm

should have been recreated. Try

$ less /var/spool/mail/jrm

again. If everything is fine, try once again with your client. If it 
works this time, the file is corrupted. Bad luck day. If it doesn't, it 
is authentication.

You can

$ mv /var/spool/mail/jrm_save /var/spool/mail/jrm

at any moment.


Beware, I haven't actually tried all of these in this sequence. But I 
have done all of these one day or another. The spooler directory is 
special, so you might have to do one or another as root; and / or chown 
a file here or there.


Good luck,

Uwe
