[Logicmail-devel] Unnecessary roundtrip when using PLAIN for SMTP AUTH

[Ken M. <mu...@an...>]

LogicMail 2.x treats SMTP AUTH using PLAIN and LOGIN the same, in that 
it only sends a response when challenged by the server.  In the case of 
PLAIN, this results in an unnecessary roundtrip.  SMTP AUTH with PLAIN 
allows an initial response to be sent as an optional argument to the 
command:

AUTH PLAIN <Base64 credentials>
235 2.0.0 OK Authenticated


as opposed to:


AUTH PLAIN
334
<Base64 credentials>
235 2.0.0 OK Authenticated
