Replying to my previous email with some more information:

[ltsampros@laptop]outbox $ ls -1 | grep -vi new | sort -n | awk -F" " '{sum = sum + $0} END {print sum}'
117121

The sum of all the article numbers in the outbox is 117121 while it
should have been 117855 (sum of all integers between 1 and 485).

Which means there is more than 1 mail missing from that folder. Do you
think that such article holes play a role in the above problems I'm
facing?

Thanks,
