There is only one Mailwasher - from Firetrust.
Please explain in more detail what happened.
[snip]
Correction. *Three* times they have bounced worms to me. I found another
in my email archives. (I haven't yet found the one that was successfully
disinfected by my ISP's filter. I may have zipped in in my mail directory
on my Internet account without having downloaded it yet.)
In both cases, the origin was an IP address that has *nothing* to do with
my ISP (all IPs in 192.75.95.0/24) but had its hostname forged in the HELO:

Note that pine on my ISP's system couldn't decode the attachments as they
were included as plain text (and that is probably also why the virus
filter couldn't delete the "attachment" even though it claimed "This
message has had one or more attachments removed" -- this problem has since
been fixed once I pointed it out to the tech team). HOWEVER (!!), there
are a number of mailers out there with broken MIME handling (webmail
applications that include a footer with unquoted '=' characters in a
message sent as quoted-printable is one offender) that result in messages
that pine can't decode. A recommended workaround is to download the raw
messages and use UUDEVIEW or a similar utility to extract the attachments.
In the case of the Firetrust messages, UUDEVIEW successfully decoded and
extracted the infectious worms and the bounces from Firetrust could have
caused a less suspicious user to get infected.
Oh, and good luck on getting any contact information for them from a
whois lookup.
