After reading the Wiki on problems with using Bayes in SA, trying everything in
the suggestions, I decided to debug the code. I found what I think is a mistake
in the parsing of mbox type mailboxes. On lines 531 and 595 of
ArchiveIterator.pm are the lines:
if (substr($_,0,5) eq "From ") {
last if substr($_,0,5) eq "From ";
which has as a result that no messages are found because the substring that is
contained in an mbox mail message if "From:" not "From ".
Thus, the fix is simple:

529c530,531
< if (substr($_,0,5) eq "From ") {
---

> if (substr($_,0,5) eq "From:") {
593c595
< last if substr($_,0,5) eq "From ";
---
> last if substr($_,0,5) eq "From:";
