I have a problem with receiving email from major email servers such as Apple and Twitter. My server can receive email from Google but I have no idea why the mail which Twitter send to me has not been received. When I review maillog under /var/log directory, I couldn't find any error or even any logs.
I have tried to clear the log file. When I send an email from gmail to my mail server, I can see mail logs. But when I send an email from Twitter, I can't see any logs.
Is there anyone here to help me? I can provide extra information which you want.
