Today I added SMTP support to NDSMail. This means you can send mails with NDSMail.
Now you can actually send and receive mails on the toilet !!!
I was even able to send mails while I was waiting at the mannheim train station. Thanks T-Com/T-Mobile ! (And, this service is free :)
For those who want to give it a try (please be aware that it is still an unfinished version, use at your own risk)
