Hi,

 

i am unable to recieve an email from specific domain, upon troubleshooitng i found the following error :

STARTTLS=server, error: accept failed=-1, reason=unknown, SSL_error=5, errno=104, retry=-1, relay=somedomain.com [1.1.1.1]

 

is it could be because of TLS profile or do i have increase the cipher level ?

am unable to understand the error message here .

    Do you have a TLS profile  for sending?

     

    Are you enable for TLS for  receiving ?

     

    But yes if you are some one is trying to  use TLS and the  system are not compatible, the MTA will fallback or even deny mail as determine the policy ( required or  preferred )

    yes you  need  delivery rule  to use TLS outbound. Typically you write it as  *.somdomain.com and set the TLS   and method.

     

    Download the   fortimail cli and administration guide for your version of FML and follow the guidelines. Keep in mind that NOT all  MX support TLS or even have it enable.
