I'm not sure I see this adding a huge amount of value to our security. If a vulnerability is found in any of the major SMTP engines then surely the people trying to take advantage of it will be aware of this fixup? What's to stop them ignoring the obscured header and trying the vulnerability...

Sorry, did forget to mention that we're NATing.

I recently joined a company with a very badly configured network infrastructure - particularly in the area of security, DNS, DHCP and address space. At the moment we're using a mass of ranges which cross networks owned by INTEL, EDS and the US gov as the "network admin" has assinged entire...

Thanks for the answers. Very useful. The server is running at a branch office and I don't have very much control over the way things are configured. One further question. When I telnet to the mail server via the internet (rather than from the RDP session to the server itself) I occasionally...

...and telnet to port 25 (telnet localhost 25) I get a good SMTP header and quick response. When I try the same thing from the Internet I get: 220 *********************************************************0****0****0 *********************200**0*****0***0*00 helo domain.com 250 mail.domain.com...

I have a box with Fedora 6 and Samba on it. I've created a share with the following config: [global] wins sever = 192.168.1.10 workgroup = Richtest server string = Linux test server netbios name = Linux security = share [datashare] path= /datashare writeable= yes guest ok=yes I've also set...

I have a user writing a lengthy report in Word 2003 who is experiencing some problems with page numbers. She has a large multi-page table which she would like to insert in landscape while the rest of the document should be in portrait. She inserted 'next page' section breaks and added the...

The company I work for generates a large number of scientific reports and other documents. We opperate from a standard template which contains toolbars and autotext to help people with symbols and complex formulas but I would also like to provide a custom dictionary. Ideally when one scientist...

I have a workstation which is shared by several users with different accounts. I would like to prevent those users from being able to lock the workstation as this prevents others from logging in. Can anyone tell me a good way to do this? I've looked through the local security policy on the...

I have a user with Outlook problems. We are running 2003 with all the latest service packs, but when he closes Outlook something is not working correctly. A process called Outlook.exe continues to run and it cannot be reloaded untit this process has been ended. I resintalled the whole of...

On our phone system we have several huntgroups used for incoming calls on our main office number. When the system goes into night service calls are forwarded to the voicemail box of huntgroup 250 (also known as MainHuntgroup). When messages are stored in this voicemail box I would like the...

I've been thinking about purchasing a Blackberry device for remote access to email, but there's one part of the technology I'm not sure about. I understand that the Enterprise server monitors mailboxes and forwards information, but I'm not sure about the small business implementation. All I...

We have an Avaya IP 403 phone system with around 20 handsets. The handsets are all located in our open plan office and users have repeatedly asked if I can vary the ringtones. There is an option in the management software to change the internal and external ringtones, but when I've tried to...

I have two Exchange servers. One is my primary server, which has recently been completely rebuilt due to an OS problem, and a temporary server. For the rebuild I moved all my users (about 25 of them) onto the temp server and changed incomnig email to the new server. I followed all the MS...

That's definitely well worth knowing. Our main group has four users, but the overflow has thirty-one. If I change the main huntgroup to overflow to two smalelr groups and split my thirty-one users between those two, will that cure the problem? Many thanks

On the main group call waiting is off by queueing is on. On the overflow group (if it matters) call waiting and queueing are both on.

Okay, to clarify. We have a main huntgroup which contains the office manager and the receptionist, and an overflow group, which contains everyone else. Everyone has an indivicual direct number and a main number calls the main huntgroup. If no one answers on that group the incoming call is...

We have an IP Office 403 system with 6 ISDN lines connected. Incoming calls on our main number call a huntgroup which contains our receptionist and office manager. If this huntgroup is not answered then calls overflow into a second group containing everyone else. This works fine if the first...

I would like to do some basic stuff with ASP but I'm not exactly sure the best way to get to what I want. I have a common homepage for all users with links and other useful data on it. I would like to add timezones at the top of the page so people can quickly find out what the time is in LA or...

Its Win2K SP4 with most of the MS updates installed, and Exchange 2000 SP3.
