SMTPUTF8 is required, but was not offered by host - with Kaspersky Secure Mail Gateway

[Rodrigo de Chile]

We have installed Kaspersky secure Mail Gateway V 1.1.2.30 and from one day to the next certain emails began to bounce with the following message:
SMTPUTF8 is required, but was not offered by host w.x.y.z [w.x.y.z]
where w.x.y.z is the IP number of the Mail Gateway solution.

I have looked for information and postfix has a configuration parameter for SMTPUTF8 but that from the console I cannot find or does not exist.

Something similar has happened to someone and how did they solve it?

Hi.

 

No, but you can  you share your maillogs? 

Also, can you try to enter in Technical Mode console and execute:

• echo smtputf8_enable = yes » /etc/postfix/main.cf
• postfix reload

Check again your maillog and send share again here.

 

Cheers!
