Question

Thunderbird无法连接到Postfix / Dovecot 我的webmail界面使用login（name@domain.tld +密码），
传入（SSL / TLS，端口993）和传出消息（STARTTLS，端口587）我做了一些调试，并且知道它必须是证书错误请问这里有人知道如何解决吗？
这是我使用SSL调试的mail.log：

这是我的Dovecot ssl-config文件（/etc/dovecot/conf.d/10-ssl.conf）：

# Log SSL problems
verbose_ssl = yes

ssl = required

ssl_cert = </etc/dovecot/dovecot.pem
ssl_key = </etc/dovecot/private/dovecot.pem

ssl_protocols = !SSLv3 !SSLv2

ssl_cipher_list = EDH+CAMELLIA:EDH+aRSA:EECDH+aRSA+AESGCM:EECDH+aRSA+
                  SHA384:EECDH+aRSA+SHA256:EECDH:+CAMELLIA256:+AES256:+
                  CAMELLIA128:+AES128:+SSLv3:!aNULL:!eNULL:!LOW:!3DES:!MD5:
                  !EXP:!PSK:!DSS:!RC4:!SEED:!ECDSA:CAMELLIA256-SHA:
                  AES256-SHA:CAMELLIA128-SHA:AES128-SHA

ssl_prefer_server_ciphers = yes

Dovecot的SSL证书是为localhost设置的当我尝试将我的root ca和domain cert整合到dovecot证书中时，问题仍然存在：
dovecot.pem证书 = dovecot证书内容+域名证书内容+ root ca证书内容（完全按此顺序从上到下）
dovecot.pem密钥 = dovecot cert密钥+域名证书密钥+ root ca证书密钥（完全按此顺序从上到下）

Answer 1

Thunderbird希望dovecot能够为其提供验证连接所需的证书（中间证书或自签名CA证书）。查看http://wiki2.dovecot.org/SSL/DovecotConfiguration中的“链式SSL证书”。

您可以通过将中间证书添加到SSL证书文件（/etc/ssl/certs/imap.pem或您的ssl_cert）指向的任何位置来解决此问题。如果您从供应商处获得了SSL证书，则应该有关于如何获取中间证书的说明。

Thunderbird无法连接到Postfix / Dovecot。 Webmail有效
