what happens when you do it without compression? As a test, try:
tar cf - Mail | tar tvf -
Then, if that works with no problems:
tar czf - Mail | tar tzvf -
If that works, the only thing left that I can think of is serious disk problems... let me know if those commands report errors or not though...

Does the corruption happen with different sources to tar/gzip/bzip2?
I am now testing some other sources. It seems to happen with large files.
Does while archiving in verbose mode appear any error message?
No, the archiving itself does not give any messages. The testing does.
What are the commands you run?
$ tar cvzf mail.tar.gz Mail
or $ tar cvjf mail.tar.bz2 Mail
For the testing I use: $ tar tvzf mail.tar.gz or $ tar tvjf mail.tar.bz2
Compression errors often occurs because of bad/damaged RAM.
I do not seem to have other problems, which you would expect with bad or damaged RAM.
