Re: E-mail problem

Hi Tom,

Firstly thanks for your response.

I am sending it from itu.edu.tr

Yes, we have spf records and also other smtp precautions such as dkim and
so on.

We use sendmail, so we have sendmail conf and macro. Also, we have cipher
restrictions.

Nevertheless, the cipher which has successful communication with
mail.openbsd.org is allowed on our mta. Meanwhile this cipher
is ECDHE-RSA-AES256-GCM-SHA384.

Thanks.
Berkay
