Hi,
This failed with the error message:
2004-11-06 15:33:25 sasl_cram_md5 authenticator failed for 
([192.168.9.1]) [192.168.9.1]: 535 Incorrect authentication data
2004-11-06 15:33:25 sasl_plain authenticator failed for ([192.168.9.1]) 
[192.168.9.1]: 535 Incorrect authentication data

192.168.9.1 is configured as not a relay host of the mail server.
The cyrus(2.2)-imap (with sasl2.2) configuration is as follow:
admins:  cyrus
allowanonymouslogin:  no
allowplainwithouttls: yes
allowplaintext: no
altnamespace: no
autocreatequota:  10000
configdirectory:  /var/db/imap
drachost:  localhost

#sasl_pwcheck_method: saslauthd
sasl_pwcheck_method: auxprop

Authenticator of Exim is configured as follow:
.....
sasl_cram_md5:
       driver = cyrus_sasl
       public_name = CRAM-MD5
       server_set_id = $1
sasl_plain:
       driver = cyrus_sasl
       public_name = PLAIN
       server_set_id = $1
Exim is compiled with cyrus-sasl2.2 support.
I've been working on this issue for more than a month.
Any suggestion is highly appreciated.
Thanks
Sam
