Below is a link to an oversimplified summary of some of the copywright issues a site like this faces. It doesn't directly address the question of whether it's ok for anyone to re-publish or use someone else's "regular" email; however, it indirectly addresses it by pointing out that sites such as this should have a policy on who has the copyright on members' postings. This implies that the default assumption is that any writer/artist/creator retains a copyright. (I'll get back to this a little later).
One recommended approach is to leave copyright ownership with the poster but create an implied license for other members to re-post as long as the original meaning is retained. Which raises an interesting question of what policy, if any, MDC has on this particular issue. The MDC copyright policy being discussed here doesn't cover this. My guess is that it is part of the User Agreement.
Returning to the question of whether and when copyright protection attaches to an ordinary electronic document such as an email, my understanding is that digital works are protected when saved in some sort of tangible medium, such as CD, DVD, etc. Since MDC has no way of knowing whether the original writer has protected their work the safest policy is to prohibit the "re-publishing" of a work in whole or in part but rather to allow a summary or recap.
Additionally, due to privacy issues and the potential for claims of libel or slander (by the author's subject, if not the actual author) then the copyright issue cannot simply be resolved by having the MDC poster identify and credit the author.
Note, at the dawn of the information highway the law seemed to err on the side of "fair use" and tended to assume that anything distributed in electronic format was intended to be re-published, re-distributed, etc. Probably because it was so easy to do and hard to prevent. The emphasis has shifted, probably in the interest of encouraging freedom of expression, creativity and the dissemination of ideas.
One more thing to keep in mind, as unlikely as it may seem that ordinary electronic documents like letters and emails would routinely be kept in tangible format I imagine that a fair number of people routinely save all kinds of documents as a back up. Furthermore, in the world of academia, (which is the OP's situation) you never know who might be saving any or all of their work with the intention of re-working it and putting it a paper, article, book, etc.

Then maybe they shouldn't teach writing. It's part of the job, every job has it's downside.
