Sieve login issue. Please help.

[Müfit Eribol]

Hello,

I am a happy user of cyrus-imapd for years without any major problem 
for  small user base.

Currently, I am having login problem for sieve. I have been trying to 
find the problem for days.

Please find below information about my configuration:

1. Installed software: cyrus-imapd-2.4.17, postfix-2.10.1, 
cyrus-sasl-2.1.26, cyrus-sasl-plain-2.1.26, cyrus-sasl-lib-2.1.26 on 
CentOS 7.

2. Authentication is done through saslauthd, pam and mysql.

3. pwcheck_method: saslauthd, mech_list: plain login

4. There is no problem with login to imapd or smtpd.

5. cyrus.conf

}

10. When I try to login using smartsieve

maillog:

Sep 22 10:38:32 server sieve[16029]: STARTTLS failed: localhost[127.0.0.1]

I don't understand why STARTTLS is being called when connecting from 
localhost? Is it normal? Obviously, I am doing something wrong.

I would appreciate any help. Thank you.
