Sounds like a problem with postfix talking to your XP client, not a dovecot problem. If you've changed the tls settings in postfix recently, you likely broke compatibility with older clients. If you need further help, feel free to ask on the postfix-users list. Be sure to include "postconf -nf" and "postconf -Mf" output, along with related log entries demonstrating the problem. http://www.postfix.org/DEBUG_README.html#mail -- Noel Jones > > dovecot -n as follows: > > # 2.0.9: /etc/dovecot/dovecot.conf > # OS: Linux 2.6.32-504.16.2.el6.x86_64 x86_64 CentOS release 6.6 (Final) ext4 > log_timestamp = "%Y-%m-%d %H:%M:%S " > mail_location = maildir:/home/vmail/%d/%n/Maildir > mail_max_userip_connections = 50 > namespace { > inbox = yes > location = > prefix = INBOX. > separator = . > type = private > } > passdb { > args = /etc/dovecot/dovecot-sql.conf > driver = sql > } > protocols = imap pop3 > service auth { > unix_listener /var/spool/postfix/private/auth { > group = postfix > mode = 0660 > user = postfix > } > unix_listener auth-master { > mode = 0600 > user = vmail > } > user = root > } > ssl_ca = </etc/pki/dovecot/certs/intermediate.pem > ssl_cert = </etc/pki/dovecot/certs/dovecot.pem > ssl_key = </etc/pki/dovecot/private/dovecot.pem > userdb { > args = uid=5000 gid=5000 home=/home/vmail/%d/%n allow_all_users=yes > driver = static > } > protocol lda { > auth_socket_path = /var/run/dovecot/auth-master > log_path = /home/vmail/dovecot-deliver.log > postmaster_address = postmas...@starionhost.net > } > protocol pop3 { > pop3_uidl_format = %08Xu%08Xv > }
