Does bad server space or IP address affect on Search Engine Ranking? Specially Google?

I think the website on which i m working is located on a server which is having spamming problem because whenever i send mail to some one it goes to spam folder.

Also when i tried to use squidoo.com's lense services it gave me following error message

"Squidoo access from your IP range has been blocked, due to an unmistakable trend of spam or automated lensbuilding or other Terms of Service violations coming from the area. Our Squidoo engineers work hard to keep the platform safe and valuable for the hundreds of thousands of people who use it to publish useful, unique, curated, authentic content.
