[Kshowmail-user] About the email deletion bug published in MozillaQuest Magazine

[Gustavo Z. S. <gz...@ca...>]

Well. Article says that if you do not want your emails deleted, do not 
use kshowmail.
I think it is not that way.  In my case, I am the only one that has the 
password for my email account.  Mozilla is set to not to check for 
emails automatically.  I check for new emails first with kshowmail, and 
after I deleted unwanted and kshowmail's spam filters trapped emails, 
then I get wanted emails from my pop server with Mozilla and Mozilla 
will delete the whole list from the server.  There is no way kshowmail 
will delete emails by mistake.

I think that probabilities that kshowmail will delete other emails by 
mistake will only occurr if:

- More than one user receive emails in the same email address.
- The email client will delete some emails, not all from the pop server.

Oh! Now that I am thinking about this problem, I found a potencial way 
that it will really happen.  Let me see...  Yes.  It happens:

- Kshowmail checks for new emails and for example it finds 3 new emails.
- I run Mozilla Mail and get those three new emails.  Mozilla deletes 
those 3 emails from the pop server.
- Kshowmail still thinks that I have 3 new emails as per its own list
- Let's say I forget that I have already downloaded those 3 emails with 
Mozilla. Then I return to kshowmail and see those 3 new emails there.
- I decide to delete the first one ( email number 1).
- But, meanwhile a new email has arrived and it will be listed as number 
1 becasue my email box was empty.
- kshowmail proceeds to delete email number 1

- It will delete the new email.

Then,  The only way to be sure what email kshowmail will delete is 
working with UIDLs the pop server assigns to each email and not with the 
sequential numbers assigned for each pop session.

Conclusion:  numbers can be assigned by kshowmail after sorting by date 
and time.  That means that numbering emails is not important.  Each 
email should be treated by its unique UIDL number.
