i got a similar error: > May 11 21:00:57 mail smtpd: 1dce957aa81938f4 smtp connected > address=22.214.171.124 host=co1gmehub09.msn.com > May 11 21:00:58 mail smtpd: dnsbl: 1dce957aa81938f4 not listed > May 11 21:00:58 mail smtpd: 1dce957aa81938f4 smtp disconnected > reason="io-error: handshake failed: error:140260C1:SSL > routines:ACCEPT_SR_CLNT_HELLO:no shared cipher" the "fix" from eric worked, i received the email, thanks! this is kind of funny, the email was from microsoft, i had to send them an email that they remove me from a block list cause apparently my neighbors aren't behaving peacefully and have sent some spam, so microsoft decided to block the whole network, which prevented me of sending emails to @hotmail.com addresses this is the third time i had to send them an email (first time was half a year ago, second time about 3 months ago, i am seeing a pattern here... enough with the anectodes) it seems like they are sending emails using some legacy ciphers?! before 6.9 i received these emails without any change in my smtpd.conf
