Several days' worth of emails were automatically purged from the inbox on my Blackberry (a Yahoo account) recently. Is that normal? All but the last two days were wiped out. Is there an auto-delete for old messages or something?

This was an 8830 World Edition, BTW.

from messages go to options=> general options=>change # of days to keep messages


How much memory is left on your device???if its too low. here =>messages disappearing

hope this helps
