I have Self-Serivce (univention.com/2015/12/self … n-ucs-4-1/) portal to recovery my password for all users. My UCS Master instance is setup in Amazon AWS / EC2 and until month ago all was working fine with sending a mail. Now UCS could not connect to gmail - my mail domain/server. Probably Amazon block some connection to this SMTP. I have done some research and all suggestion are point to SES in Amazon.
My question is: Do you know how to setup USC Postfix to use SES Server like a Relay host? Or maybe there is different possibility to setup it?
Thank you for any help and answer.
