[Dovecot] eudora issue

[kent crispin]

There seems to be a protocol mismatch between eudora and dovecot when 
using pop.  The login interchange with, for example, mozilla, is as 
follows: 

MO: [connects]
DC: +OK dovecot ready.
MO: CAPA
DC: +OK
DC: CAPA
DC: TOP 
DC: USER
DC: UIDL
DC: RESP-CODES
DC: STLS
DC: SASL PLAIN
DC: .
MO: USER yyy
DC: +OK
MO: PASS xxxxxxxx
DC: +OK Logged in.

But with eudora, with apparently equivalent configuration, the sequence
is as follows:

EU: [connects]
DC: +OK dovecot ready.
EU: CAPA
DC: +OK
DC: CAPA
DC: TOP
DC: USER
DC: UIDL
DC: RESP-CODES
DC: STLS
DC: SASL PLAIN
DC: .   
EU: auth PLAIN AG1tcgBtaXN0bGV0b2U=
DC: -ERR Unsupported authentication mechanism.

At this point eudora reports an error back to the user, and the 
connection fails.  Can anyone shed any light on this?  Is it just that 
there is an incompatibility in how eudora and dovecot view the 
protocol?  Or is there some configuration option I need to tweak to 
make things work?

Thanks for any help.
