New issue 542 by thuga... at ...626...: gb.net.smtp auth plain fails due to  
addtional "\r\n"
http://code.google.com/p/gambas/issues/detail?id=542

1) Describe the problem.

I have an application that tries to sends email using gb.net.smtp. Sending  
the email fails because the host returns:
Response code: Authentication credentials invalid (535)
Responce parameter: 5.7.8 Error: authentication failed.

Sending email to the same server using Thunderbird works and comparing  
things using a tcpdump log I see that both base64 plain auth strings are  
the same only gb.net.smtp has some additional characters. Decoding these  
string I see that they match only gb.net.smtp has at the end  
additional "\r\n".

Looking in the libsmtp_connection.c source I see that indeed "\r\n" is  
added so I commented out that and recompiled gambas. Tried again and I can  
successfully send the email.

Looked at the Internet to see if there are any specs on adding "\r\n" to  
the auth string but could not find that. The examples I found, for instance  
https://tools.ietf.org/html/rfc4954 show no "\r\n":

$ perl -MMIME::Base64 -MDevel::Peek -e 'Dump  
decode_base64("dGVzdAB0ZXN0ADEyMzQ=")'
SV = PV(0x1811878) at 0x1813990
   REFCNT = 1
   FLAGS = (TEMP,POK,pPOK)
   PV = 0x182e270 "test\0test\0001234"\0
   CUR = 14
   LEN = 16

The server I am using is smtp.vodafonevast.nl which according to the  
Service ready message (220) is smtp01.glasoperator.nl ESMTP Postfix
