Each time you send and receive attachments, Gmail automatically scans them for viruses.

If a virus is found in an attachment you've received, our system will attempt to remove it, or clean the file, so you can still access the information it contains. If the virus can't be removed from the file, you won't be able to download it.

If a virus is found in an attachment you're trying to send, you won't be able to send the message until you remove the attachment.

You can use your google mail account SMTP to send mail from any of your email addresses, even on the go using a mobile pda. This is fantastic news for people who are costantly traveling on different networks and having to switch smtp servers.

This probably is not that important to a lot of you but for those who understand it, it is great news. I am copying it from here

* Log in to your Gmail account.
* Click 'Settings' along the top of any page, and then select the 'Accounts' tab.
* Click 'Add another email address' in the 'Send mail as:' section.
* Enter your full name in the 'Name:' field, and the email address you'd like to send messages from in the 'Email address:' field.
* Click 'Next Step >>,' and then click 'Send Verification' to complete the process. Gmail will send a verification message to your other email address to confirm that you'd like to add it to your Gmail account.
* Now go to your e-mail client software to setup your e-mail account.
* Under e-mail address, use one of the verified e-mails you've added to your Gmail account.
* Under outgoing mail smtp server, use smtp.gmail.com. Since it requires SMTP authorization, use your Gmail account as username (e.g. yourname@gmail.com) and your Gmail password as password. You can turn TSL on or off.


My Added Note: Make sure to switch your SMTP port to 465.
