Email Application with Security settings and Alternatives

I would like to set-up my company email in the Email app on my android device (Exchange server). After completing the set-up, it asked me for security update in which it lists lots of warnings such as erasing all the data on phone, etc. I got scared from these as I am not sure whether the IT dept would have all those privileges on phone or not.

Alternatively, I tried to set up an alias with my Gmail account to send email from my Gmail and it looks like it was sent from my company email, but I don't have the SMTP server address (I tried my best to get it, it seems that the exchange server doesn't have one).

Any alternative to use my company email on my android without give all these permissions to take control of my phone without my knowledge?

My phone is Samsung S3 GT-I9300 with Android 4.3
