Re: [Quantlib-users] Some list mails missing

[U.Mutlu <um...@mu...>]

Luigi, your below posting of today morning as well I did not
receive but found only in the archive.

Normally in case of such problems the sending mail server tries to
resend it later, but your mail server seems not to try to resend it.

Look what google says at 
https://support.google.com/mail/answer/6596#zippy=%2Crecipient-server-did-not-accept-our-requests

It says "Try sending the email again later.", ie. the user has to do it 
manually. That's very funny :-)

"
"Recipient server did not accept our requests"
Why your message bounced
You'll see this error message if Gmail can’t connect to your recipient’s email 
server.

What you can do
The problem usually goes away quickly without you doing anything. Try sending 
the email again later.

If you keep getting the error:

Check if there are any mistakes in the recipient's email address.
Contact the customer support team of your recipient's email provider.
If you got this error while emailing someone at your work, school, or other 
organization, contact your administrator.
"

I checked my server, but could not find anything related in the logs.
I now have disabled IPv6 as I don't need it on that server, and rebooted the 
server.
I will also contact my hosting provider about this problem. Thx.
