25 gigs at mailbox.org will run you EUR 3.50/month. Plus you get calendaring/contacts, proper CardDav/CalDav and GPG built in. They've been providing email for 27 years and run the email infrastructure for many companies large and small. Plus, your email would be running on renewable energy and their bank account is with a socially responsible bank (yes, such things exist).
