When you send an email with SMTPClient, you have to specify a server - aka 
a relay - you want to use to deliver emails. 
I just downloaded the SqueakMap image and it's using localhost as the mail 
server. Localhost has a mail server set up, but it's probably not 
configured properly to forward emails to mail.squeak.org.
Probably the best would be if SqueakMap sent mails directly to 

I don't know who installed exim on that machine and why, but it was very 
likely a mistake and unless there is an explanation for it (nothing in the 
admin log), I'll remove it soon.

That's quite complicated. When you connect to an SMTP server, the first 
command is EHLO (or HELO), in which you claim your domain name. That is 
the first thing the server will verify (along with your IP address) based 
on information available in DNS.
If you try to send an email from the SqueakMap server directly, you'll 
fail right at this point, because that server is not a legit source of
@squeak.org emails according to the DNS records.
