TLS Problems

We've found that Debian 7's version of OpenSSL has problems interoperating with some other SSL implementations. Here are some things you can try:

1. Add this to the end of /etc/mail/sendmail.mc:

   --> LOCAL_CONFIG

   --> dnl # Do not allow SSLv2 and weak ciphers

   --> O CipherList=HIGH:MEDIUM:!ADH:!MD5:!SSLv2

   --> O ClientSSLOptions=+SSL_OP_NO_TLSv1

   
   After you add the above lines, type:

   --> make -C /etc/mail && /etc/init.d/sendmail reload

2. If that doesn't help, you have to disable TLS with the machine gwmail.bradescoseguros.com.br. Put this lines in /etc/mail/access:

   --> Try_TLS:gwmail.bradescoseguros.com.br NO

   
   and again:

   --> make -C /etc/mail

3. If that still does not work, you may have to disable STARTTLS for now by removing
   --> include(`/etc/mail/tls/starttls.m4')dnl from sendmail.mc
   and running

   --> make -C /etc/mail && /etc/init.d/sendmail reload
