How do I block Yahoo Groups invitations from coming into my inbox?

Joseph: How do I block Yahoo Groups invitations from coming into my inbox?
I get yahoo groups invitations to porn sights every day. I want to block them but as they are from yahoo groups you can’t even mark them as spam. I’m at a loss. Yahoo doesn’t answer the phones or answer E-mails so I feel stuck.

You …me…and hundreds of others…I haven’t tried it yet, but you can give it a try…

1st….go to ABOUT.COM and enter” Finding the IP Address of An Email Sender” in their search box. They give a great explanantion of IP addresses.. Reason for this is as follows

When you open up the message sent to you by YAHOO GROUPS go to the bottom of the email…right side…and click on FULL HEADERS..This will bring up a bunch of goobly gook that contains IP ADDRESSES..After reading what ABOUT.COM says about IP ADDRESSES you “might” be able to pick the right one to enter in to the BLOCKED ADDRESS box after you click on OPTIONS…MAIL OPTIONS…go to the left side of the screen and click on SPAM once in there you add the IP ADDRESS in the box…go above and click on SAVE CHANGES…will this do it…don’t know yet, but I am going to try it the next time I get one. If you find that it works you can pick this as the best answer….=))…and tell me if it worked. Sure hope so…good luck

NOTE: Please remember to pick the best answer by clicking on the THUMBS UP at the end of that particular answer…thanx

If you did not ask for these mailings, then treat them as the spam that they are. Yes, Joseph, you CAN mark them as spam. You can also block the address that they come from. If you can’t spam them, then try this: sign out of Yahoo. Then delete your temporary Internet files, history and cookies, some computers need to reboot. Once done, go back into Yahoo and see if that has helped. Now, you can not completely stop all spam, but you can help to put a big dent in it.
First, try not to open any of them, that only makes them send more and more to you.
Check mark them and click on ‘Spam,’ this should stop those addresses from being delivered to your inbox.
Use your spam guard and block address.
Look for the ‘Options’ link at upper right corner of mail screen and click on it
Options /mail options
Click on ‘spam’ in the list on the left.
Make sure spam guard is on, by checking in the little box.
Then in ‘Blocked Email Addresses,’ enter the E-mail address you wish blocked, in the box after ‘Add a blocked address’ and click on the ‘add’ button, then click on save changes at top left of screen.
You will never get mail from that address again.
This should help you to control your spam.
Other tips:
Never open E-mail unless you are absolutely sure who it is from.
Never give out your personal information to anyone.
If you are on a site and you absolutely have to sign up for something, check the entire page to make sure you uncheck any lines wanting to send you any other info, notices, catalogs, ads, and the like.
Added detail:
Yes, spammers change one item in their addresses a lot, so you might try blocking the entire domain, by putting in
*@ thedomainyouwanttoblock.com
for instance: *@seeyou.com
Or, if they change the domain, instead of the company name you can block the name by putting in Imatheft_inc@*
Hope this helps.
