How do you say "mehmet@yahoo.com"? Nokta is ".", but what is "@"?

turkish people say it as "et" , similar with the pronunciation of "at" (æt) in english, just written in turkish way. if you have to describe it you can say: etrafında yuvarlak olan a, süslü a, eposta a´sı

That is logicai. Sana minnettarım.
