I am becoming irritated by irregular inexplicable email delays. Today the same originator sent me 3 emails at 8.47, 8.36 and 8.49.
They reached my talktalk mailbox at 8.52, 10.21 and 13.00 respectively.
They sent me another at 16.07 which arrived at 16.12
(I have still got one they sent me at 8.51 on 9/9/21 which arrived at 8.51)
firstname.lastname@example.org sent me an email at 7.51 which arrived at 13.09
Some days I am sent an automated email at 14.00 which requires a prompt response. Recently these have been arriving as late as 03.49 the next day.
I realise that network delays can be caused by all sorts of things, but the uncertainty is becoming a nuisance. I would blame external routing delays if it wasn't for the billing message!

Situation seems to have returned to normal now. At least there is some sort of explanation.

I realise that the sporadic nature of the delays will make investigation difficult, but I could provide some more examples of message headers.

I'm not sure that there's anything that we can do about this but would you like me to ask our email admins if there's anything they can see that could be causing the delays?

It is the address I use for the community. Yesterday an item sent at 1616 arrived at 1804. Another sent at 2025 arrived at 2104. Today the routine 1400 message arrived promptly at 1401. Then a message sent at 1615 arrived at 1724. It’s baffling and a bit annoying.

There’s no pattern. Today’s 1400 message arrived at 1413, then a message from another originator which was sent at 1616 didn’t get delivered until 1804. (They send me an SMS as well as an email.) The community notification for your previous reply arrived at 1558, but I can’t tell when it was sent because I am accessing my email using my phone, not my PC at the moment.

This morning at 0348 a time sensitive message sent yesterday at 1400 finally arrived. The originator sends messages to me at 1400 on three days each week. They usually arrive promptly. Their business process requires a response within 2 hours; a positive response triggers a further email.

In case it helps anyone here are the headers from TalkTalk's own message

It seems to have spent a long time at nec.momentum.opaltelecom.net before proceeding to aa.mta3vsmtp.cc.prd.sparkpost
This morning a routine message sent to me at 8.52 arrived at 9.59. There could be another one from the same originator on its way.
Last night one sent at 22.21 arrived at 23.02.

I did note one inbound mail message to the TalkTalk Mail platform delayed by 2 hours and a few showing delays of a few minutes to 9 minutes. The vast majority though were delivered in a timely manner.
Sometimes delays are simply due to excessive demand for access to the MX servers receiving inbound mail. Busy times or sometimes a denial of service operation. Mail can also be deferred for inspection if CloudMark believes it needs to scan the message and attachments.
Email is offered on a best endeavours basis and most messages get a timely delivery. Delays for a lot of messages can be the pre-cursor to a fault condition so it's useful to know of widespread issues. TalkTalk would investigate those.
TalkTalk may need to view email headers that contain server addresses and timestamps showing up where delays happen. Please have these ready if TalkTalk call for them.
