Hello List

Sorry about the long post.

I am trying hard to get to understand my /var/log/maillog when
connecting to cyrus-imapd.

When I open Evolution and connect /var/log/maillog says:
Oct 24 21:52:33 dell2600 imaps[15186]: starttls: SSLv3 with cipher DHE-RSA-CAMELLIA256-SHA (256/256 bits new) no authentication
Oct 24 21:52:33 dell2600 imaps[15186]: login: testbox.mydomain.com [] me at mydomain.com DIGEST-MD5+TLS User logged in SESSIONID=<dell2600.bradcan.homelinux.com-15186-1382647953-1>

What does the first log entry above "no authentication" mean? Imediatly followed by User logged in!

TIA, Charles Bradshaw

I'm using Evolution for testing configured like this:
  IMAP port 993
  SSL encryption
  SMTP port 587
  TLS encryption
  DIGEST-MD5 authentication
