Email Encryption
Aug 8, 2007
I have a client that is in need of a easy to use and transparent as possible method of sending encrypted email to many external clients.
They have currently been using verisign digital ID's and have not been satisfied with the amount of work necessary to send and receive encrypted email.
I would welcome any and all installable or 3rd party service recommendations on how to handle this. The would prefer that their cleints receiving the email have to do the least amount of work, in order to receive their emails.

I am just trying to understand RSA encryption.
Just say I have three parties Alice, Bob and Eve.
All parties have access to Bob's Public Key.
Alice is going to send Bob an encrypted message of either "1" or "0" (without quotes)
Eve manages to intercept Alice's message.
If Eve encrypts "1" and "0" using Bob's Public Key, will one of them be the same as Alice's encrypted message?

Can anyone who is a security expert recommend the most secure option for choosing what type of "cipher" to use with our OpenVPN setup?
(I bolded the one I think might be best? Let me know what you think. We are currently using "BF-CBC", but I want to be sure it's not breakable...) ...

Are there solutions to sync folders between local and remote servers with file encryption capabilities. I mean:
<source server, unencrypted> <----sync-----> <remote server, encrypted>
I need sync similar to rsync, secured data transfer and encrypted storage on a remote server, so even root won't be able to access the data.

As I understand it, PGP Desktop is not compatible with server os's. Also, TrueCrypt and BestCrypt containers have i/o overhead. What else is left? Environment is 2008 Server with high i/o throughput requirements..

I believe there is a gap in my understanding of VPS with regards to just how much control you really have over the system. VPS gives you "root access" which typically means top-level access... but in reality, the true super user is a boot-up console user. Few VPS providers that I've investigated offer console access to your VPS while booting.
What, than, can be done about system upgrades or using advanced features like root filesystem encryption? Say, for instance, that my provider offers openSUSE 10.1 and I want 10.2. I would be loath to do such a thing if I can't reboot and watch things as it goes. What if the upgrade failed and you need to drop to a single-user mode to fix it?
Or maybe my real misunderstanding here is that you can't upgrade a system in a VPS if the provider doesn't offer the upgrade?
And what if I want my entire system (other than a boot partition) to be encrypted. This would include an encrypted root and swap. This also requires a password at bootup well before any services (like sshd) start.
Again, maybe the real answer is that I can't do that at all anyway and so it doesn't matter.

I'm contemplating creating a website that could store extremely sensitivity information. It's more than likely that a MySQL database would house this information.
My question is. Does anybody have any experience when it comes to encrypting an entire server disk?
I've searched online with disappointing results.

What's the go with seeding the PRNG on windows as there isn't dev/random or dev/urandom? Should I use CryptoAPI or just use a file with random contents and change it often, or just leave the PRNG to "almost" randomise itself?

I have plesk12 set up but when i set a mail (dovecot) password, it gets stored in plain text (which I can verify by running /usr/local/psa/admin/sbin/mail_auth_view ). I would like to change this default setting to be encrypted.

I'm trying to migrate old server into a new server.
Both uses plesk 11.5.30 version.
I'm using the "Migration & Transfer Manager" for importing everything but it does not work. The error is
Error: launchpad error (Error code = 2):
== STDERR ====================
Unable to start SSH session: Unable to exchange encryption keys
==============================
Seems like an ssh problem but ssh from shell works fine in both directions.
I tried also to create public key and put into authorized_keys with no luck..

I'm having difficulty sending an email to another email address (with a different domain) which is on the same VPS.The trouble is, on the other domain's VPS control panel, within the DNS settings, the MX records have been pointed externally (to an exchange server). Their email is turned off. But bizarrely, their mailbox is full.
It seems as though Plesk is ignoring the MX records, and sending MY email internally to the OTHER domain's mailbox on the same VPS.How do I get Plesk to send my mail to the correct EXTERNAL MX records?

I had a email address I deleted on my server (postfix on Debian 4), but to my surprise the server still recieves email for the address!
(I have manually tried sending a email to the address and it comes througt).
I have deleted the address from the /etc/postfix/virtual file and restarted postfix.
What could I have forgotten?

One of my customers asked me if is possible technically to offer free email services.
Since he's going to launch a big portal he want to offer such things later, for all users.
Now, there are problems as:
a) if there is any possibility to compress emails similar with GMAIL or YahooMail or so, because i can't imagine the email is uncompressed
b) how can be handled email boxes over multiple (mail ?) servers if the HDD space needed would be larger than for one server HDD ?

I am having an email issue and I can not resolve. I am hoping for some assisstance here.
One of my local clients are not able to email each other in their office. (About 10 employess I believe)
They are using Outlook mail client, and using ISP's SMTP server. They are able to send/recieve email to other users externally, but not intenally.
Using webmail works perfectly fine.
I spoke with my host and the said everything is working fine. I checked with the ISP to see if they are blocking the IP address on the SMTP server. They said they were not.
I have a personal account on the same server and tried to send email to another local email account, and it did not work either. Tried to send email to my clients email and they did not recieve anything.
I am on the same ISP as my client, so Im still not sure if its the ISP or not.

I setup mail piping with Exim so that e-mails sent to a specific account be forwarded to my PHP script. It's not working properly, because when I send a mail to this account, it's bounced by the mailer daemon:
Code:
This message was created automatically by mail delivery software.
A message that you sent could not be delivered to one or more of its
recipients. This is a permanent error. The following address(es) failed:
pipe to |/home/user/public_html/support/parse.php
generated by support@mydomain.com
local delivery failed
In my /etc/valiases/domain.com file I have:
Code:
support@mydomain.com: "|/home/user/public_html/support/parse.php"
*: :blackhole:
What can be causing the error?

On one my servers, I'm receiving hundreds of spam emails that are clogging up the email queue to email addresses that do not exist.
For instance domain.com, I would get
bob@domain.com
liz@domain.com
325235@domain.com
You get the picture. How do I setup my server so that if there isn't an email address setup the email automatically gets deleted instead of trying to attempt to deliver it?

I have a client who has his own hosting account, and wants to leave his e-mail on his own hosting account, but his website on my hosting account.
On his own hosting he has created a sub domain called shop, and pointed its A record to the IP address of my server. On my server I've setup his domain name, and created the sub domain shop. That all works fine.
The problem I have is that the site under the shop domain needs to send an e-mail to sales@hisdomain.com. Now my server thinks the main domain is setup on my server, so it sends the e-mail to itself.
I'm justing wondering how I can get the server to point the mails back to his hosting?
A previous host I've used said they had to add the domain as a remote domain on the server, then they had to make some changes to /etc/localdomains because I was getting errors trying to send mails to the address.

I currently have a domain on Server 1 (Linux, Apache, Ubuntu, Matrix control panel).
This server does not have any spam filter, so I have moved all the email accounts to Server 2 (Linux, Apache, Fedora Core, Plesk) which does have a brilliant spam filter; and have changed the DNS record for mail.domain.com to the IP address for Server 2.
Emails are being successfully received on Server 2.
On Server 1, when an email is sent through SMTP to an address at that domain, it does not send it to Server 2, it gets delivered to the hosting account for the domain on Server 1. So what I am guessing is happening is that Server 1 detects the domain has an account on the server, and instead of looking up the DNS info for that domain, just assumes it is on Server 1.
What I need to do, is force Server 1 to send email for that domain to Server 2. Is this possible, and if so, how can it be achieved? If more info about the server is required for a solution please let me know and I'll provide what I can.

I have a Windoze box with three ip addresses and running Mailenable Professional as the mail server software. I do not run any DNS, rather I set up the domain to point to my server at the registrar. All of a sudden I'm getting returned mail, "This server requires PTR for unauthenticated connections". When I run the diagnostics on the mail server it says that none of my ip addresses have reverse dns....... I'm confused, what do I need to do at the registar and server level to feel joy again?
