IOERRORS -- the saga continues

[Perry Smith]

I have tracked down my problems to a call to sasl_decode in prot_fill.

To recap: I am getting IOERROR: unexpected end of file in my log  
file.  It turns out that if the client has Kerberos GSSAI  
authentication and the client tries to do an "APPEND" command, it  
frequently fails (but not always).  The rest of my Kerberos stuff  
appears to be fine.

The APPEND is sent across to the server.  The client can be set up to  
do LITERAL+ or not.  The client sends all of the message in either  
case.  The server reads all of the packets.  Usually the first  
packets go through the sasl_decode and result in valid text.  But  
after the first block (4096) or so of data, the remaining data is  
lost and sasl_decode reports back that there is only two valid  
characters.  No errors are reported back (that I am aware of).

I ended my quest at this point last night and I probably will not  
pick it up again.  For now, I can work around the problem by  
switching to plain authentication and just set up a VPN before using  
mail.

I hope this helps whoever follows in my footsteps...
