It looks like you have specified PLAIN as your only mechanism 
within imapd.conf, and I'm guessing you have 'allowplaintext: 
yes' set as well.

LOGIN is more typical within SMTP connections, so I would add it. 
I'm not aware of any equivalent 'allowplaintext' option within 
Postfix. I don't think you need one.

You will also need to create a SASL config file for Postfix which 
matches this configuration, to get similar authentication 
functionality. Typically, you'd create the file 
'/etc/postfix/sasl/smtpd.conf' and put these lines into it (I 
would add LOGIN):

mech_list: PLAIN LOGIN
pwcheck_method: saslauthd
auto_transition: no
saslauthd_path: /var/spool/postfix/var/run/saslauthd/mux

however, if you are running your postfix chrooted, which appears 
to be the case, then you'll want to change that last line to:

saslauthd_path: /var/run/saslauthd/mux
