Title:
  Postfix/openssl not accepting Signature Algorithm:
  sha512WithRSAEncryption

Status in “openssl” package in Ubuntu:
  New

Bug description:
  Hi,

  since we recently upgraded a mail server to latest ubuntu packages the
  mailserver does not accept certificates recently generated with
  openssl anymore.

  When trying to connect with SMTP-TLS and client-cert, the server
  aborts and logs to mail.log:

  Sep 24 22:40:37 mail postfix/smtpd[17022]: warning: TLS library
  problem: 17022:error:0D0C50A1:asn1 encoding
  routines:ASN1_item_verify:unknown message digest
  algorithm:a_verify.c:146:

  
  It works with older certificates using 
      Signature Algorithm: sha1WithRSAEncryption
  but not anymore with newer ones using 
      Signature Algorithm: sha512WithRSAEncryption

  
  regards
