Change Icon when Mail was sent successfully

[florianbaer]

First of all, thank you veeery much, you saved me (as a student) from paying a fee (which is always not easy as student)

would it be possible to change the icon when sending a mail from warning to something like a success-icon?

Hi, glad you like it. I will look into it in the future, now it is not critical issue.
