I do not get some e-mails

Hi,

When I register with some pages tells me to send an e-mail to activate my account and I do not get e-mail that they sent and if I do it with another account goes smoothly.

thank you all!

I am sure that there is anti-virus or firewall on your mail provider.

yahoo and many more scan messages, and if anyone has the virus, removed it directly and not warn you.

thanks for the interest,

Is there any other reason for this?
