Is there a mail alias for ... ?
The school has a system of mail aliases controlled with the mlalias command.You can get a list of all the mail aliases (there are a lot of them) with the command mlalias -l.
There is also a web interface which allows you to examine the mail aliases and a list of useful School mlaliases.
Please remember though, think carefully about which list you send your mail to. People tend to get very annoyed about receiving mail on list which is inappropriate. Think, "does everyone on the cse@cse alias need to read about my COMP1011 enrollment problem?"
In addition to those aliases listed by mlalias -l, there are Virtual aliases created from the udb. These include aliases such as comp1011-list which contains all the students (and staff) for COMP1011.
