+TargetMilestone: ---
+Summary: SmtpClient uses AUTH LOGIN even when unavailable
+Please fill in this template when reporting a bug, unless you know what you
+are doing.
+Description of Problem:
+Steps to reproduce the problem:
+1. Run the snippet below and connect to an SMTP server that doesn't
+   allow AUTH LOGIN
+2. Result is SMTP status code 504 with the exception below
+Actual Results:
+Exception thrown-
+   System.Net.Mail.SmtpException: 504 5.3.3 AUTH mechanism LOGIN not available
+  at System.Net.Mail.SmtpClient.Authenticate (System.String Username,
+System.String Password) [0x000a4] in
+  at System.Net.Mail.SmtpClient.PerformAuthentication () [0x00074] in
+  at System.Net.Mail.SmtpClient.Send (System.Net.Mail.MailMessage message)
+[0x000c5] in
+Expected Results:
+Should be able to successfully login as it did in 1.1.18 (presumably
+choosing an AUTH method offered)
+How often does this happen? 
+Every time
+Additional Information:
+Didn't try versions in-between, but OS/Sendmail[8.13.7] versions didn't
+change.  Only change was upgrade from Mono 1.1.18 to Mono 1.2.3
