	Have you read through the FAQ, or searched the FAQ for terms like

	That's the envelope sender that Mailman uses when sending out 
mail for a mailing list named "testlist at mailman.sghms.ac.uk".

	So that any bounces will come back to the correct address where 
Mailman can automatically process them.

	Not without breaking Mailman, no.

	See above.  Search the FAQ for terms like "performance".

	Since you're using Exim as your MTA, all performance tuning 
questions regarding it should be directed towards their mailing 
lists, and you should also search their online documentation, FAQs,
