Hello all!,

I try use the yast mail on SLED 12 SP1, but the options for configuration is not complete.

I want configure manually postfix (by example http://serverfault.com/questions/521362/how-to-relay-mail-via-google-account-using-postfix), but i receive some problems, this occur only with SLES because, i use RedHat Enterprise Linux 6.7 for my weblog and postfix operate OK.

These are my actual errors:

I see, that the normal files not exist in SLED in comparison of RHN. by example: /etc/postfix/tls_policy

I want configure with this installation, because if try uninstall the default postfix zypper or yast want uninstall a lot of applications.

I want configure because i’m use a testing software but i can’t use the mail for sent the passwords or bugs issues (testlink and mantis bug traker).

thanks in advance.

[…][/QUOTE]

the messages seem to indicate that you have opted for TLS encryption, while not having set up the according framework. Any postfix startup messages, i.e. complaining about not being able to access the certificates? The SF article only shows the steps required for your upstream connection, you’ll need to add the base configuration for TLS as well!
