    One or more computer sending email SPAM


    Apparently there are 1 or more PCs in the network sending out spam. I do not use a local email server. I have outlook from Office365 subscription

    How do I find the culprit? I have a Draytek Vigor 2830.

    I have tried:

    - Wireshark looking at [ tcp.port == 25 ]
    - Bitdefender Security suite scan on networked PC's

    :)

    why is my windows phone sending spam emails over 5000 to be exact

    Your Windows Phone does not send spam emails. The spam emails probably originate from a spammer who has got the login details for your email account. This means he can send them from anywhere..

    Hi renkun.


    Can I ask how you know this?

    I ask as MS sends you a weird message when you first get an account and the words lead to that conclusion but all they really want is to verify you.

    Have you checked your sent items to see if it is coming out of your mailbox? You really need to do a through malware scan by using the info in this link. Read Run Me First Malware Removal Guide (incl. Spyware, Virus, Trojan, Hijacker) | MajorGeeks.Com Support Forums After reading the instructions, seehttp://forums.majorgeeks.com/showthread.php?t=139681 This will give you even more information.

    Nothing should be using Port 25, since pretty much every ISP is using SSL/TLS and ports 587 for SMTP, 993 for receiving if the Windows 10 app may be set up with spam botting. Now you can also go into your gateway logs and see if it shows any issues. Net Tools is a really good program to put into your arsenal.

    Wireshark is a really good program for sniffing out issues. That you can also get from Major Geeks website.
