Hello,
I found if peer MTA's timestamp is too much different from my end, the
messages may not be displayed.
for example, when you try to sign up to apache projects' mailing list,
like one of this page:
https://flink.apache.org/community.html
The response message's (for user to confirm) timestamp is 12 hours ahead
of me.
Thus some email servers won't display the response messages correctly
(even no response messages appear in the inbox).
At least GMX's mail servers have this issue, as well as web.de. anyone
can test for it.
Can you give some suggestion?
Thanks.:)
