Dear Support team,

We are using Iredmail as our scan 2 mail server, however some of our printers Ricoh IM c300 doesn't work with iredmail and what we see on the printer is SSL negotiation failed.
When I check on the server logs I see that there is an issue with ciphers library no shared ciphers can be negotiated between the printer and the server.
I tried to add some ciphers as below:
smtp_tls_ciphers = ECDH+AESGCM:DH+AESGCM:ECDH+AES256:DH+AES256:ECDH+AES128:DH+AES:ECDH+3DES:DH+3DES:RSA+AESGCM:RSA+AES:RSA+3DES

it didn't change anything.

Here is my postconf output:
