cultavix Posted March 30, 2005 Share Posted March 30, 2005 I am having a really weird problem. I am running Windows 2000 Server Sp3 and Exchange 2000 and trying to run SMTP. For some reason, after I start running it for a while, I get like 100 connections to the internet to different SMTP serers around the world? It looks totally like some type of hack or a virus or something? I am going to try updating Exchange....but in the meantime, does anyone know what could be causing this? Thanks! - Jimmy Link to comment https://www.neowin.net/forum/topic/302754-windows-2000-server-exchangesmtp-problem/ Share on other sites More sharing options...
LPC Posted March 30, 2005 Share Posted March 30, 2005 Are they incoming or out going connections ? Link to comment https://www.neowin.net/forum/topic/302754-windows-2000-server-exchangesmtp-problem/#findComment-585696984 Share on other sites More sharing options...
+BudMan MVC Posted March 30, 2005 MVC Share Posted March 30, 2005 Exactly are they incoming or outgoing? Look at your queues! I would say your server is busy sending SPAM! ;) Whats the IP of this server? Have you checked to see if its open to relay? I would guess its listed as a open relay.. Whats the IP?

cultavix Posted March 30, 2005 Author Share Posted March 30, 2005 The connections are all mostly outgoing, TWO of them are incoming. That's what is so fishy about this. And yes, the computer is open to relay to everyone.... Thanks for your help! Edit: Also, I checked the queue and it was really full. PS- Only 2 people use this SMTP server...

+primortal Subscriber² Posted March 30, 2005 Subscriber² Share Posted March 30, 2005 of those 2 pcs, have you scaned them for virus or spyware? It possible that either or both of those machines are zombies and sending spam. Or your exchange server is and open relay to the outside and other people are using it for sending spam Link to comment https://www.neowin.net/forum/topic/302754-windows-2000-server-exchangesmtp-problem/#findComment-585697069 Share on other sites More sharing options...

+BudMan MVC Posted March 30, 2005 MVC Share Posted March 30, 2005 Dude I PM'd you -- yeah looks like you got it locked down so nobody can send mail - get denied by policy, you need to set it up so your local machines can send mail, etc.. And you have to setup the domain you accept mail for, etc.. Let me know what domain your suppose to hosting mail for, etc.. since I did not see a reverse for the IP you sent me (only one of them was listening on 25) And quite a few domains will NOT except mail from you when you do not have a reverse, etc..
