Download from Multiple “Mail Userid” accounts

Is it possible to have Postie check multiple email accounts for postings?

We would like to have our users be able to post via email to different parts of the website.

The easiest way for them to do that would be to have an email account for each type of post. for example:

To post news items we would have them send an email to [email protected]
To post events we would have them send an email to [email protected]

Is this possible with Postie or is there a better way to do this that is also intuitive for our users?

Thanks,
Rich
