first of all, please keep the list CCed on every email. The point of this is
to serve as a reference for future users facing the same issues as you.

Exim has nothing to do with POP3 (or IMAP4 for that matter); it can only
speak the SMTP protocol.

Evolution is not connecting to the Exim server at that point, unless it's
trying to send some email that was left undelivered in its outbound email

Please see RFC4954 for more details on SMTP authentication with SASL.
Generally, it goes like this:
S> 220 mail.example.com ESMTP Exim 4.71 Sat, 25 Sep 2010 06:53:54 +0300
C> EHLO adsl-234-123-234-123.isp.com
S> 250-mail.example.com Hello adsl-234-123-234-123.isp.com
S> 250-SIZE 52428800
S> 250-AUTH PLAIN LOGIN
S> 250 HELP
C> AUTH <method> ...
S> 334 ...
...and so on.

Something else is probably happening whenever you reinstall Exim, regardless
of the version. Both Exim versions can do inbound and outbound SMTP
authentication, either with SASL, or by using certificates.

Generally speaking, when it comes to email, there are two kinds of protocols
used: SMTP, which is used when a MUA (such as Evolution) or an MTA (such as
Exim/Postfix/etc.) tries to *send* an email *to another MTA*, and POP3/IMAP4
which is used by an MUA when trying to retrieve emails that are already
stored on another server. As I mentioned earlier, Exim cannot speak
POP3/IMAP4, that is a job for programs like Dovecot/Courier/Cyrus.
I need some more details on your setup before I'm able to further assist
- What are you trying to achieve by using Exim? Assuming this is a single
user setup, the simplest thing to do would be configuring Evolution to speak
to your ISP's SMTP and POP3 servers directly.
- Which servers is Evolution configured to speak to at the moment.
As you can see, we're shooting at the dark without this information.
