As a someone with multiple domain I might also agree with you however the OP did not state if they were looking for person email, or a system for handling email from a domain. Without knowing this important detail, it is difficult to target the advice. Perhaps the OP can tell us what kind of email access they are looking for. Personally I like the Linux VPS solution, however I have Be at home with a static IP address to roll my own from there at the moment, I will probably move to a VPS if this proves unstable, however I like my current setup of OpenBSD spamd grey trap, is there an equivent to this for linux?<br>

<br>
IMAP is good, POP3 is acceptable, and webmail is a nice-to-have.<br>
<br>
What is really important to me is that the service is reliable and as<br>
much 'future proof' (if any such thing exists) as possible: meaning I<br>
don't like the idea of having to change my email address simply because<br>
I am changing who provides that service.<br>

<br>
I don't want to simply get my email from my broadband provider because<br>
(usually) the name of the provider features in your email address and it<br>
becomes a total hassle to swap providers.<br>
<br>
As I said, I'll contemplate going with gmail if I have to. But, I was<br>
thinking of getting my own domain and piggy-backing the email on it.<br>
<br>
The thing is, I have never done this before and I don't know a) how to<br>
go about doing it; b) good service providers; and c) what the potential<br>
gotchas are.<br>
<br>
At this point in time I don't have the resources to run the email server<br>
from home, so I need to purchase the service from someone.<br>
<br>
Thanks for your help<br>

Date: Wed, 6 Apr 2011 09:40:04 +0100 (BST)<br>Subject: [Gllug] Getting required read / write / access permissions<br>Hello,<br>
I am trying to get the correct access permissions automatically for a<br>
number of users accessing a server running Debian Lenny at present, with all<br>
users accessing the server from Microsoft PCs via Samba. The requirements<br>
are personal home directories with R/W access only by the owner, a directory<br>
with full recursive R/W access to all files to all, but only all, on a<br>
restricted list, plus a directory with full recursive R/W access to all<br>
listed users. Individual users need to be able to create sub-directories and<br>
new files. Some users also need access from their normal computers via<br>
OpenVPN. It would be best if shared files can not be deleted once created.<br>
I have created two additional groups (not users), one restricted, the<br>
other to include all. I have edited /etc/samba/smb.conf to set access<br>
permissions to 770 on each of the directories, together with the required<br>
user lists for each. If I look at man chmod I see that I can specify 770 but<br>
there are six possible attributes, rwxXst, and when I use ls -al I only see<br>
three.<br>
I am still being told that not all the required users have write access<br>
to all neccessary new files. Have I missed something? Would Microsoft<br>
limited access permissions over-ride those set by Samba?<br>
<br>

Yes, they do, but that should already be there if it's a half-decent ISP.<br>

Absolutely - and even better - will allow you to change that reverse<br>
DNS accordingly at whim. We do - all done through our control panel.<br>

Very simple and standard to create in samba. The example configs should<br>
be sufficient.<br>

<br>
Are these to be separate shares or two directories on the same share?<br>
If the latter, then POSIX acls are possibly the best tool.<br>
<br>

<br>
That last bit is simply not possible. If users have sufficient<br>
permissions to create files, they have sufficient to delete them. It is<br>
possible to set up a situation where users can modify the contents of<br>
files but not create, rename or delete them but that's very little use<br>
in real life.<br>
<br>
> Some users also need access from their normal computers via<br>

<br>
That doesn't make much sense. OpenVPN gives people access to a network,<br>
not to a computer's files. How are the OpenVPN users going to be<br>
accessing the files after they have gained access to the network via<br>
OpenVPN?<br>

<br>
Can you post the relevant parts of smb.conf? Anything relating to<br>
access permissions in the global config, plus the share sections.<br>

<br>
I think you need to read up on Unix file permissions and then re-read<br>
the chmod man page.<br>

Too little information. That would need to be looked at on a case by<br>
case basis, eliminating problems as they are discovered, till there are<br>
no more problems.<br>
