Re: [Declude.JunkMail] OT - iMail 7.x and Windows 2003
I don't see that as a big issue. They can't Auth when 'Account Access Disabled' is checked in the user gui. If the user has a POP box, uncheck 'Account Access Disabled' and use their unique password. If the user is for forwarding, then make sure that 'Account Access Disabled' is checked. They can't Auth, so they can't send.

Re: [Declude.JunkMail] OT - iMail 7.x and Windows 2003
I have seen some root kits be able to hide from tools like F-Port and such. As you have suggested using a packet capture tool usually always helps identify which port they are exploiting. However, with that said the one thing that I keep as a golden rule is once a box has been comprimised is that its going to be scratched. You just never know what else the left on the machine.

Re: [Declude.JunkMail] OT - iMail 7.x and Windows 2003
One other thing to add to this. Ipswitch in their brilliance, decided to make a default password of "password" for any newly created account including root. One must take great care to change these otherwise they can become susceptible to AUTH hacking with a great deal of ease, and you then become essentially an open relay even though you are configured not to be.

RE: [Declude.JunkMail] OT - iMail 7.x and Windows 2003
Actually, we have tried both but have not found the culprit(s) yet. Although my partner believes he saw a spike in traffic coming in as a Telenet session from an unexpected origin - rrcs-74-39-200-122.nys.biz.rr.com which on searching with google appears not too uncommon - that is hacks, spam and spyware from users of biz.rr.com. This has us planning to try to isolate which IP address(es) attacks may be coming in on and shut them down. Regarding telnet - apparently there is a problem with windows 2003 and iMail. If my source is correct one can telnet into a Windows 2003 system running iMail (pick a version) on port 25 and get by the authentication. Again, my source told me that neither Micosoft nor Ipswitch has come up with a way to stop this. It appears only to be a problem on Windows 2003, not Windows 2000.

Re: [Declude.JunkMail] OT - iMail 7.x and Windows 2003
I think that the exploit is in imail 7.07 and not in your server do a google on imail 7.07 exploit. So you most likely would need to upgrade to 8.2 series. Tho the exploit isn't in 8.15 I don't believe. BTW they do seem to have some interesting pricing going on if you google imail deals depending on your number of domains and users.

It is still alive and well, and in fact continues to be improved and upgraded. The next version is in active beta as we speak. The only thing that has happened is Ipswitch no longer sells Imail as a stand alone product. SA are still available for it.
