Newsletter confirmation

[mnemos]

Hello,

I've problem I don't know what to do with it.

Here is the situation.

PR Manager in my company sends a newsletter. He receives confirmation and statistics in Campaigns -> View Status, but this statistics differ from Google Analitics. In mail he put links to articles which are not linked from main site. In Sugar statistics he get that i.e.: 1 person viewed mail (what does it mean? how sugar gets an information?)when there were 100 receivers of newsletter but in Google analitics he can see 267 entering to this link.

Why those statistics differ so much?
What mechanism uses SugarCRM to get confirmation?
What it means that person viewed mail?
Can Sugar i.e.: translate links in mails and add generated ?id=mail_receiver_id or something like this?

Second question is important because my SugarCRM server is in local network and there is no mail redirection to this server so there is no way to send an info to this server by mail form outside.

Thanks for help and sorry for my English.

Viewed mail = mail, viewed (opened) by the user
Confirmation = an image with an ID, I believe (the Sugar server needs to be accessible by the receiver, otherwise Sugar cannot register this)
