One of the techs at Comcast got back to me directly, so they know about it.
I’m sure it’s a shitty day for them, so good luck, we’ve all been there.
Sadly, as you all probably know once it gets fixed, they’ll probably be slammed
with incoming emails leading to longer delays.
Sincerely,
We're seeing issues as well for both mx1 and mx2:
delivery temporarily suspended: lost connection with
mx2.comcast.net[68.87.20.5] while receiving the initial server greeting
delivery temporarily suspended: connect to mx1.comcast.net[96.114.157.80]:25:
Connection timed out
Thanks,
Matt
Seeing a lot of this:
Connecting to mx1.comcast.net [96.114.157.80]:25 ... failed: Connection
timed out (timeout=5m)
Connecting to mx2.comcast.net [68.87.20.5]:25 ... connected
H=mx2.comcast.net [68.87.20.5]: Remote host closed connection in response
to initial connection
My guess is that mx1
We have been seeing errors regarding concurrent connections etc. and have
tuned our outbound servers down as low as we can go for these domains, yet
have not been able to consistently deliver mail since mid June.
None of the normal channels seem to be working. Anyone on this list seen
the same
Yes, seeing a lot of timeouts and delayed mail for Comcast traffic in the
last few hours.

Are they getting any email over IPv6 at all?

Yeah, seeing the same. Looks like it's been going on for about 4 hours
now.

Seems like they are having some smtp issues, lots of timeouts on a few

Philadelphia, Montreal, and Paris so doesn't seem regional.

I've mentioned
Years ago when i worked in support, we regularly had customers with
hotmail/live mail-addresses that were not receiving mails from us,
especially mails with links to reset their password for our controlpanel.
According to our logs, the mails were delivered fine. Hotmail accepted
it, and then it

The problem is that the mail does not arrive either in spam or in the inbox.
This happens for most of our ip's.
Can anyone
Have you tried setting up SNDS and JMRPP for your networks?
Have you tried opening a ticket with Microsoft?
Are you authenticating your mail properly?
Lots of useful information here:
https://sendersupport.olc.protection.outlook.com/SNDS/index.aspx
Does it produce a bounce?
We see cases where eg Recipient verification on MS365 customers simply does not
work (apparently depending on which cluster they are hosted). Instead of
rejecting with some 5xx it will bounce later.

Hi,
I've got a customer running their own mail server who is
experiencing huge delays on *receiving* emails from btinternet.com
senders.
This is ongoing, and appears to be affecting all email to them from
all senders with a btinternet.com address. My customer is not
noticing any attempts by BT
