I have installed ISPConfig 3 on CentOS 5.5. I have all the services running fine with Dovecot as IMAP server. I am getting below error in maillog. fatal: no SASL authentication mechanisms I have used dovecot-2.0-0.18_114_rc3.el5.x86_64.rpm dovecot-sieve-0.1.17-5.el5.x86_64.rpm I am not able to login the squirrelmail. It gives error as "Unknown user or password incorrect".. Please can someone advice me.
1) Did you follow exactly the perfect server installation guide? 2) Which exat error message do you get in the maillog?
