I was having an email discussion regarding my postdoctoral application with my potential host supervisor. At one point, he asked for recommendation letter from my PhD supervisor.
When I contacted my PhD supervisor, he asked me to forward the above-mentioned email correspondence to him. So, I forwarded my email discussions with postdoc host to my PhD supervisor. The mail didn't contain anything related to postdoctoral project, but only on official matters like interview timings etc. My supervisor has sent his recommendations to the postdoc host in the same email track. I wanted to know is it unprofessional from my part?
Recent Update: I came to know that my PhD supervisor wrote a simple email instead of a formal letter with his signature and stamp. Moreover, he mentioned only my first name with wrong spelling (e.g. 'Dr. Jahn', instead of Dr. John Smith). He also asked the postdoc host if he could collaborate with him in the same email. The email doesn't contain anything bad about me but the structure of it looked naive to me. Can anyone suggest anything regarding that?
