here is the dovecot -n dump

dovecot -n # 2.0.19: /etc/dovecot/dovecot.conf # OS: Linux 3.8.13-xxxx-grs-ipv6-64-vps x86_64 Ubuntu 12.04.2 LTS ext3 auth_mechanisms = plain login mail_location = maildir:/var/mail/vhosts/%d/%n mail_privileged_group = mail passdb { args = /etc/dovecot/dovecot-sql.conf.ext driver = sql } protocols = imap pop3 lmtp service auth-worker { user = vmail } service auth { unix_listener /var/spool/postfix/private/auth { group = postfix mode = 0666 user = postfix } unix_listener auth-userdb { mode = 0600 user = vmail } user = dovecot } service imap-login { inet_listener imap { port = 0 } } service lmtp { unix_listener /var/spool/postfix/private/dovecot-lmtp { group = postfix mode = 0600 user = postfix } } service pop3-login { inet_listener pop3 { port = 0 } } ssl = required ssl_cert =

netstat -la -pute | grep dovecot tcp 0 0 *:pop3s *:* LISTEN

I dont like the "port = 0" but thats what was mentionned in the tutorial

so I changed /etc/dovecot/conf.d/10-master.conf /

service imap-login { inet_listener imap { port = 143 } ... }

service pop3-login { inet_listener pop3 { port = 110 } ... }

now

I think the issue is with authentication

There is "no auth attempts", so you do not have an issue with authentication.

Because of the "TLS handshaking: Disconnected" it looks like the connection gets cut during the initial TLS handshake. To debug this, first increare logging, then try from localhost without encryption, e.g.:

telnet localhost 143 1 login "loginname" "password"

and watch the human friendly output. Terminate the IMAP connection via

2 logout

Maybe that client does not like your SSL cert and drops the connection thereof? Or maybe a firewall thinks it has to fiddle in, e.g. change Thunderbird to use SSL on port 993 instead of STARTTLS on 143.

Kind regards,

any help plz

anvil logs wont help much, look for your connect from: lines, it should show your connecting IP, and few lines after it detailing what it is doing, I suspect you may have the same issues as with dovecot, never ever ever force ssl on clients unless you know what you (and they) are doing, and not knowing what version you are using makes it more difficult.

Should be using postfix 2.10.1 (the latest) " smtpd_tls_security_level = may "
