Can I use iOS mail without SMTP?

Question

Greetings,
I am using iPhone 5s and iPad Mini, both with iOS 8.3.
My question is this: Can I use something other than the iCloud SMTP server in order to use the native iOS mail app on my iPhone and iPad? (i.e. [email protected])
I work for a public company that offers free wifi to its customers. Our IT staff blocks email over SMTP so that people can't come in and use our wifi to send spam/junk mail through our servers. I have Gmail and Yahoo addresses that I would like to condense into my one iOS address. But since I spend a majority of my day at work, I am not able to send or receive messages due to the SMTP blockage. This does not affect iCloud.com which is accessed through a hard wired connection on my desk, but I am not always at my desk, hence the need for iOS mail portability.
I've checked online for an answer and can't seem to find one. I was told by our IT staff to configure the mail setting to go through a cloud server instead of SMTP but I don't know if that's possible.
I would appreciate any information or insight you can offer.
Thanks and best wishes,
-Jason

You do not get to pick which servers to use when you subscribe to someone else's email service. Gmail, Apple, Yahoo, AOL, Hotmail, MS Live all use SMTP to send from their user accounts.  You can use any of those systems with the iOS mail app, but they all use SMTP relay to send from your device to their internal mail sending system (which may not use SMTP, but the only way for you to get an outgoing mail into their system is to use SMTP). If your company blocks all SMTP traffic, then you'll never be able to send from a subscriber email service on a wifi device with a dynamic IP.
You also cannot "condense" (whatever that means - merge?) any other proprietary email service you use (like Gmail or Yahoo) with another proprietary email service like Apple's. These are separate services run by independent companies.
You should be able to use your browser to use Gmail or Yahoo or another service via their web interface though. When logged in via the web page, you are not sending mail from your device at all, but directly from the service providers system.
