Yahoo server uses SSL. So you cannot give standard port number 25. Use Yahoo! Mail SMTP port: 465. Check if modem support SSL connections or not. Can you attach that email manual so it will be easy to help.

Hi ajay
i try with each port 25,587 and 465
i follow this thread
http://www.edaboard.com/thread244401.html
in this thread it is mentioned that

gmail does not work with this firmware that does not have SSL encryption, then you will have problems in gmail, yahoo works well in gate 25 which is a simple SMTP door

Its better to setup an SMTP server on your PC and then try to send email. The reason why I am saying this is.. these days all public email providers like gmail/yahoo/live all uses SSL authentication. Which is not supported by modules. I am not sure about Yahoo. But I do not feel yahoo allow this on simple port coz it will be too vulnerable to hacking then. I suggest you to setup SMTP server on PC, check xampp.

Hi majoka,

I am using SIM900 module to send email and I have sent succesfully.
You should know a few points

-the firmmware version is 1137B02SIM900R64_ST_ENHANCE

- also you should use EMAILSSL=1 for yahoo and port 465

this has worked in my case.

I hope it will work for you.

good work.

Sermet
