Hello,
I’m working for 5-6 days to fix this problem but I can’t. When I try to AUTH PLAIN with an existing user (ex :myname.mydomain) I’m getting this error : 535 5.7.8 Error: authentication failed: authentication failure
But when I try to AUTH with Non existing user I see this error : 535 5.7.8 Error: authentication failed: another step is needed in authentication
I can’t find any more explation about error in Log file.
What do I need to do?
My postfix config is below.
