He guys,
i've a vb4 forum, i started it with 3.x 9 years ago until 4.x of today.
In the last months a problem was born.
Many mine users have gmail.com emails and a lot of them do not receive emails.

So the problem is that i receive a notification email like this one:

Hi. This is the qmail-send program at smtpsmart3.aruba.it. I'm afraid I wasn't able to deliver your message to the following addresses. This is a permanent error; I've given up. Sorry it didn't work out. [email protected]: 62.149.158.231 failed after I sent the message.

How i can fix this problem ?

Has your site ever been flagged before for anything negative i.e. malware or other? Are you including links to several other sites in these emails... anything you can think of to help us determine why Google is not jiving with your site at the moment?

I send the standard vbulletin notification email of course.
I don't i my web site was flagget for malware, since i don't think.
It's a forum of vw golf owner, not commercial.
How i can check if my website is in some "malware" web site list ?

If it were me, I would simply contact Google and ask them if there is anything on their end associating your site as "bad" this way you get to the bottom of it quickly, if it has been infected by malware in the past there could still possibly be something present.
