Hi Thomas,

On Saturday, October 5, 2002, 12:39 PM, you mentioned about "OT: Strange emails":

T> It is the biggest ISP in Taiwan, and it is hinet.net (.net as the TLD,
T> without .tw). www.hinet.net They used to be my main ISP when I lived in
T> Taiwan, so the recommendation to filter out everything from them is not
T> a good idea, if another user in Taiwan joins this list.

True, this is subjective depending on where you live, and what mail you
are accustomed to receiving.  I don't know the full capabilities of using
reg ex in TB!, but I do know them in Unix/Linux... It would be interesting
to see if TB! would filter on the IP address of the sender, or a block of
addresses. That would work, providing that remains constant from a few
emails that Art was receiving.  That way, hinet.net could be left intact.

G>> The 4 numbers, plus your return address, ... well, it is probably
G>> spam to begin with.

T> ACK.

A>>> The oddest part is that the email contains the text of a just received
A>>> message... yet when you re-read it the text changes to the text of ANOTHER
A>>> message in the same folder.

G>> It is probably from a spam program which is not RFC 2821(SMTP) or RFC 1652
G>> (8-bit MIMEtransport) compliant, and your ISP's SMTP does not recognize it
G>> and mangles it during receipt,

T> I would like to see that. Once a message is in the TB folder, it
T> cannot be mangled any more.

Of course, I was referring to the ISP's MTA, whether it be Sendmail,
Postfix, qmail, or 100s of others.. Once the mail is received and stored
by the ISP, and is pop'd or IMAP'd mail into TB!, it can be already
mangled from the ISP's MTA. The above 3 MTAs are fully compliant, but I
have seen this many times with non-compliant MTAs.

G>> as they (ISP) may not have an 8-bit clean extended character MTA.
G>> It could also contain java script which is not a good thing..

T> But the script wouldn't execute under TB.

Of course.   The damage was initially done from the MTA either from
hinet.net on sending, or from Art's ISP in receiving, or the spammer's
software itself.

Today's thought: change is inevitable, except from a vending machine.
