Dovecot com certificados CAcert, o Outlook não pode se conectar ao IMAP

2

Eu tenho bastante instalação padrão do postfix e do dovecot no Ubuntu 12.10. Gerei meus próprios certificados e os assinei por cacert.org .

O processo de criação de certs era como abaixo:

openssl genrsa -out mail.myhostname.key 4096
openssl req -new -key mail.myhostname.key -out mail.myhostname.csr
wget http://www.cacert.org/certs/root.txt
sudo cp root.txt /etc/ssl/certs/cacert.crt
# here Submitting the CSR to CAcert takes place
# placing result certificate from CAcert into /etc/postfix/ssl/mail.myhostname.crt

Esta é a minha configuração dovecot sudo cat /etc/dovecot/conf.d/10-ssl.conf :

##
## SSL settings
##

# SSL/TLS support: yes, no, required. <doc/wiki/SSL.txt>
ssl = yes

# PEM encoded X.509 SSL/TLS certificate and private key. They're opened before
# dropping root privileges, so keep the key file unreadable by anyone but
# root. Included doc/mkcert.sh can be used to easily generate self-signed
# certificate, just make sure to update the domains in dovecot-openssl.cnf
ssl_cert = </etc/postfix/ssl/mail.myhostname.crt
ssl_key = </etc/postfix/ssl/mail.myhostname.key

# If key file is password protected, give the password here. Alternatively
# give it when starting dovecot with -p parameter. Since this file is often
# world-readable, you may want to place this setting instead to a different
# root owned 0600 file by using ssl_key_password = <path.
#ssl_key_password =

# PEM encoded trusted certificate authority. Set this only if you intend to use
# ssl_verify_client_cert=yes. The file should contain the CA certificate(s)
# followed by the matching CRL(s). (e.g. ssl_ca = </etc/ssl/certs/ca.pem)
ssl_ca = </etc/postfix/ssl/cacert.crt

# Request client to send a certificate. If you also want to require it, set
# auth_ssl_require_client_cert=yes in auth section.
ssl_verify_client_cert = no

# Which field from certificate to use for username. commonName and
# x500UniqueIdentifier are the usual choices. You'll also need to set
# auth_ssl_username_from_cert=yes.
#ssl_cert_username_field = commonName

# How often to regenerate the SSL parameters file. Generation is quite CPU
# intensive operation. The value is in hours, 0 disables regeneration
# entirely.
#ssl_parameters_regenerate = 168

# SSL ciphers to use
#ssl_cipher_list = ALL:!LOW:!SSLv2:!EXP:!aNULL

Não consigo fazer o Outlook funcionar, o que funcionou muito bem antes de configurar meus próprios certificados (apesar de alguns avisos). Ouvi dizer que pode haver alguns problemas com o "Microsoft Mail" e o Outlook, que são mais sensíveis em comparação com o Thunderbird, mas isso não deve ser um problema.

+OK The greatest mail program is ready

Eu não entendo a parte do verify error: num = 19: certificado autoassinado na cadeia de certificados . De que maneira é auto-assinado, se eu estiver usando uma autoridade confiável do CAcert?

Eu censurei IPs e hostname porque meu servidor ainda é frágil

Também há coisas sobre o empilhamento certs para o Dovecot (no link link ). A tabela mostra esta ordem:

Certificado público do Dovecot - o que é isso?

CA do servidor SSL do TDC - é minha chave pública do cacert?

CA raiz da Internet do ETD é a raiz do cacert?

Globalsign Partners CA - o que é isso?

Por enquanto, /etc/postfix/ssl/cacert.crt tem apenas a raiz do CAcert.

Isso pode causar problemas e frear o handshake TLS?

Atualizar :

O Mail funciona com o Thunderbird, mas ainda pede ao usuário para aceitar um certificado, que é uma espécie de comportamento indesejado - o que eu não esperava ao ter certs de cacert.org

I generated my own certificates and got them signed by cacert.org.

cacert.org não é confiável em nenhum dos principais SOs de hoje. Foi uma vez com o Debian, mas foi removido lá também. Pode ainda estar em algum * BSD. Notável sem navegador, sem janelas, Android, Mac OS ... vai confiar nesta CA.

I don't understand the verify error:num=19:self signed certificate in certificate chain part. In which way it is self signed, if I'm using a trustable CAcert authority ?

Mesmo se você tiver o cacert instalado localmente, openssl s_client não usará nenhuma CA por padrão para verificar, portanto, tudo não é confiável. E, dada a saída, você inclui o certificado raiz, que está errado de qualquer maneira. Certificados raiz na cadeia são ignorados porque a raiz confiável deve ser local no sistema já.

Acabei de receber um relatório de allaboutspam.com com muitos avisos e uma lista negra em barracudacentral .

Eu achei que isso seria mais fácil, mas leva cerca de 80% da minha atividade principal e não quero pagar mais por um certificado reconhecido.

Estou mudando para uma solução de e-mail hospedada e deixando meu servidor por ser apenas um servidor WWW e uma máquina de processamento / análise de dados. Obrigado @ steffen-ullrich!
