Google Mail: advanced filtering of usernames in Search

Question

The school I attend uses Google Apps for mail; using a set system for all student email addresses.

The system is similar to this example:

11A[surname and initial]@domain.org

Is there a way to use the 'from operator' to list all emails from users with the '11A' (for example) section of the email address? - allowing me to find all emails sent from students in the same assigned group.

I would like a way to set a filter or label for the 11A group, the 11B group and so on. Anything after the group '11x' can be left - it just needs to show all emails from users with that prefix.

Thanks for your help!

Edit: If case sensitivty matters, I am specifically trying to filter emails with the prefix 11n.

Answer 1

You might just start with a search of

from:"11A"

which would include all email address with that exact phrase, you could then use NOT filters to limit any extra junk coming in.

Otherwise you'll probably need REGEX (not supported in search/filter but can get the same results using Google Docs and a sheet someone made just for this, http://www.labnol.org/internet/advanced-gmail-search/21623/. After that, this REGEX

^11A.*@domain.org

should at least get you started.
