Html signatures: how to prevent user editing

Question

I have made some .html signatures for one of our clients, and there are two things they want I can't figure out how to achieve.

One of them, the client wants the text inside the signature to not be editable by the user, that is to prevent them from accidentally changing something in the signature when sending an e-mail. Is this somehow posible?

The second issue, they said they can resize the images in the signature using the mouse. I also need to prevent this so that they cannot accidentally deform the logo or enlarge or diminish it. How can I do it? I tried setting width and height attributes to the images, but that doesn't prevent them form resizing it at will.

Any help or orientation will be really much appreciated. Thanks

Answer 1

maybe you can create an image with the entire signature, so it won't be editable.

EDIT

Take a look at this link, maybe you will be able to add the signature after the send button is click.

How to modify email before sending

Answer 2

There are a few options:

1.) If you use an exchange server, you can set a Group Policy to add a signature server level and then another to remove permissions for signature access to all users. This will give you 100% control on all Outgoing messages. This is supposed to be used for disclaimers, so in a long email chain, the signatures may wind up at the bottom of the chain, not the message. See for more info: http://www.howto-outlook.com/howto/corporatesignatures.htm

2.) Another option is to run a script. This option steers away from using Group Policy, but I believe it would require action done on user level for each person, which may be an issue in a larger company.

3.) Last option I know of is to make signatures folder read only and insert the signature file directly on each person's computer. This is a very manual process and time consuming and certainly not scalable.
