Is anyone else having issues sending emails (SMTP), both from Thunderbird and android native app. Nothing has changed, but it stopped working a couple of days ago. I have checked my settings and they are correct, but no message will send. The only way I can do it is via virgins webmail page. Email client keeps asking for a password, it's never done this before and I have not made any changes. Receiving emails fine though. Any advice greatly appreciated.
It would be helpful to see what, if any, VM error code is returned by the SMTP server in this situation. Open aCommand ShellorTerminalwindow and enter the following command whereusername:passwordis replaced with your email address and password, firstname.lastname@example.org:Y54kpX5g:
I'm running wireshark and not picking up any traffic on port 25. I ran antivirus scan, came back clean, although from what I read Spambots are very difficult to spot. I changed my password on Virgin account and now I can send emails successfully! Not sure if this is permanent solution, but I wanted to thank you for your assistance.
This will probably take you longer than you think.
Note that such spam is usually sent out direct through a router port (usually number 25) and completely by-passes your usual email service routes. Note also that if a spambot operated 24x7 sending out spam in a steady stream, it would be relatively easy to spot. Most spambots are therefore programmed to wake up at periodic intervals (hours, days or even weeks between activities), blast out large amounts of spam and then return to sleep for unpredictable periods. This invariably makes detection a much harder and seriously longerprocess as, Spamhaus, for example, may drop you from its lists after a day or two of inactivity – and you then get added back again when the bot wakes up. This could repeat ad nauseum until you find and erase the source of the spambot.
