Intermittent Email delivery failures

PapPow

Since about 1 month 2/3 of my Email are rejected. First I'm getting a "Delay" Delivery Status notification 24h after I sent the message, and finally a "Failure" Delivery Status notification 48h later.

These notifications are coming from Microsoft (postmaster@mail.hotmail.com) as I have use a mandatorymicrosoft mail account required to install the PC (Windows 8).

After a lot of investigation I figured out that all my mails go through the MS Cloud service which forward them to the swisscom mail and overwrite the MS address (name@hotmail.com with my swisscom alias (mail@bluewin.ch).

The NDN traces show:

This is an automatically generated Delivery Status Notification.

Unable to deliver message to the following recipients, due to being unable to connect successfully to the destination mail server.

I place a call to MS which send me a Database to verify the the domain bluewin.ch is NOT in the black list!!! and it is not 🙂

I place a call to swisscom which suggest me to accept a fee based, remote PC investigation that I denied 😞

As I'm sure I'm not alone with this setup, can you tell if I'm the only one facing that issue.

Any suggestion is welcome.

Thanks

That same issue is recurring since the beginning of March 2016, with the same symptom (1 email out of roughly 3 is rejected by the swisscom SMTP servers).

I assume that some swisscom people are watching this forum. If it is te case can you please raise that case to your IT personnal for what it is likey to be a "load balancer" issue.

If attempt to talk to the consummer support people is useless (they want to fix my PC -🙂

Thanks

I was trying email header analysis but that was not reall helpful: https://toolbox.googleapps.com/apps/messageheader/
