When you remove attachemants from an email message, the
email message following the one that was detached is
lost when pop3 access the email box.
I've experiences email messages lost when downloading
my email with pop3. I made the following test. The
messages wit X had an attachement that was removed
before downloading email with pop3:
11 12 13X
None was lost
21 22X 23
23 was lost
31X 32 33
32 was lost
41 42X 43 44 45X 46
43 and 46 were lost.

This doesn't happen on my system, but that may be due to the POP3 server
or format of the mail messages.
I have one idea of the possible cause though - try installing the updated
Sendmail module attached to this bug report, and tell me if that fixes it.
