I have not put the option on for read receipts so I never get anything
like that.
I have office 2003
I have about 6 accounts setup
Just a pain in the arse and unsure how to stop it doing it. Thanks for
any help
I am unsure whether this is related or not, but on Wednesday I got a
delivery failure email for an email I'd never sent.
This is not in itself unusual - almost all my spam is backscatter - but
this email was sent _from my own mail server_. Examining the logs on my
mail server I found that when I'd started up outlook, at the same time as
it logged into IMAP to check for new mail, there'd been a connection made
from my IP, using my username and password, to send about 8 emails.
That same day my friend noticed the same thing (we use the same server
for IMAP but I also use it for STMP whereas he has his own exchange
server set up) - his exchange server had logged outgoing emails from him.
Further experimentation using wireshark and tcpview has confirmed that it
is indeed Outlook sending the mails. The smtp details used correspond to
my default mail profile and if I set my default profile to a different
account the smtp credentials used by the spam change accordingly.
I'm embarrased to admit I didn't have an anti-virus installed at the time
(though I was using Windows Defender); in true barn-door-horse-bolted
style I've now installed McAfee VSE 8.5, which finds nothing. My friend
however did have an antivirus installed - Sophos, which also finds
nothing.
As a workaround I've firewalled my server so I can't actually connect via
SMTP (I'll use webmail for now) but this issue has us rather worried.
Obviously I can do a complete reformat / reinstall but in the absence of
any kind of information on how we've been compromised I'm reluctant to do
so. Hijack This! for instance shows nothing untoward.
Can anyone reccommend any useful diagnostic / troubleshooting tools for
this? Alternatively, if this issue would be best dealt with on another
group, can someone point me in the right direction?
Thanks in advance,
Philip Cass
