It's the standard Latin-1 character set.

http://www.utoronto.ca/webdocs/HTMLdocs/NewHTML/iso_table.html

In essence, it means that this line may contain special unicode characters
(e.g., accented characters, Umlaute, etc.).

More often than not it's an indication that it contains some foreign
language word.

However, the word Resume is spelled with accents... I'm not sure if the Euro
currency symbol may even use that code table.

So - be ready for false positives.

Subject: [Declude.JunkMail] Line Modifier: = ? i s o - 8 8 5 9 - 1 ? Q ?


We have received spam messages in the past whose 'To:', 'From:', 'Subject:',
and 'Sender:' lines contain the character string:

        = ? i s o - 8 8 5 9 - 1 ? Q ?     (spaces added to avoid filters)

so, we created an external filter (SUBJECT) to detect the string. Now, it
appears, this may be a bad idea, because legitimate messages with this
string are also being caught by the filter (see message header below from
'lightinguniverse.com' as an example).

Can someone verify what this character string means, and whether or not it
is okay for this character string to appear in these lines? Also, is it the
sender's mail client 'JMail 4.3.0 Free Version by Dimac' that is causing
this?

Thanks!
