Can't email send to gmail and yahoo

I tried the basicDemo form. Everything works well when using my [email]xxxx@aim.com[/email] address but when I am trying to set with [email]xxxxx@gmail.com[/email] or [email]xxxxxx@yahoo.fr[/email] nothing is received.
(mails are sent out according to debug message, but only [email]xxxx@aim.com[/email] gets throught)

No filtering on the server.
Could you tell me why it works with aim.com and not with gmail.com or yahoo.fr
Thanks,

Hi Lewis,

Assuming that the Email setups are the same then the others have to be being caught in a spam filter somewhere.

What happens if you put xxx.aim.com,xxx.gmail.com in the same Email Setup?

Usually aim is fussier than Gmail so this is a little odd. Have you checked the Gmail spam folder?

Although no filter was set, gmail.com considered my email as spam, I went to the email website (mail.google.com) and checked all messages concerned as "not spam" then everything starts working, and magically yahoo.fr as well maybe using the same database?
Thanks for your advise

Hi Lewis,

Odd but good to know (I guess that Yahoo could be getting spam filters from Google ???)
