Microsoft this week warned Microsoft 365 email senders to authenticate outgoing messages, a move prompted by Google’s recent announcement of stricter anti-spam rules for bulk senders.

“By setting up email authentication for your domain, you can ensure that your messages are less likely to be rejected or marked as spam by email providers like Gmail, Yahoo, AOL,,” the Microsoft team said. Defender for Office 365.

“This is especially important when sending bulk email (high-volume email), as it helps maintain the deliverability and reputation of your email campaigns.”

Failure to comply with newly announced email authentication standards may result in emails being rejected or labeled as spam.

Microsoft also warned that the Microsoft 365 service should not be used for mass email sending, as emails that do not follow sending limits will be blocked or sent to special high-risk delivery groups using outbound spam controls built into Microsoft. Exchange Online Protection (EOP).

Those who want to send bulk emails should use their own local email servers or third-party bulk email providers, which will help ensure good email sending practices.

Organizations that want to send mass emails via EOP will need to comply with this outbound spam protection guide:

  • Be careful not to exceed the service’s sending limits by sending emails at a high speed or volume. This includes refraining from sending emails to a large list of BCC recipients.
  • Refrain from using addresses on your primary email domain as senders of bulk emails, as it may affect the delivery of regular emails from senders within the domain. Instead, consider using a custom subdomain exclusively for bulk email.
  • Make sure all custom subdomains are configured with email authentication records in DNS, including SPF, DKIM, and DMARC.

However, Microsoft warned that even “following these recommendations does not guarantee delivery. If your email is rejected as bulk, send it through on-premises or a third-party provider.”

Redmond’s warning was prompted by Google’s announcement that it was introducing new anti-spam guidelines targeting senders of more than 5,000 daily emails to Gmail users.

Starting February 1, 2024, Google will require senders above this threshold to implement SPF/DKIM and DMARC email authentication for their domains. This measure is intended to strengthen defenses against email spoofing and phishing attempts.

Additionally, bulk senders must provide Gmail recipients with a one-click option to unsubscribe from commercial emails and promptly address unsubscribe requests within two days.

As part of these efforts to combat spam, Google said it will also closely monitor spam thresholds and, in cases where abusive mass senders are identified, will mark their emails as spam to protect users from unsolicited messages and potentially harmful.

“If you do not meet the requirements (…), your email may not be delivered as expected or may be marked as spam,” Google warned.

  1. In my 50s, in conversation with a new person, I
    would make a point of stating my age even when it was utterly unrelated to
    the subject. Nine times out of ten, they’d say with genuine surprise, ‘No –
    you’re not!’ I still state my age – 64 – in this same immaterial
    way, but these days, no one contradicts me.

    Observing other women cling to their looks feels like being a retired prizefighter; thank goodness
    I’m no longer in the ring taking all that punishment and reaching for all those prizes.
    I read in the online magazine Air Mail about the ‘revenge face’,
    which women on the verge of divorce from wealthy men splurge on before the final sundering.

    Kevin Costner is alleging that his estranged wife
    Christine Baumgartner spent $188,500 on plastic surgery in one month.
    Also in that issue, a 60-year-old actress called Lisa Rinna sports a pair of
    lips that would look over the top on Towie. On the same day I read of a 33-year-old actress called Shenae Grimes
    being trolled for ageing ‘badly’ – otherwise known as daring to display laughter lines.
    Damned if you do, damned if you don’t.

    The thing that pleases me most is that, against all odds, I’ve
    been able to make a living from the thing I love doing and that thing depends on my brain rather than my body.
    As a writer, looks are my cherry on the top, not my

    At one point in my 50s, I was so fat that a magazine printed a photo of Jabba the Hutt and said it was me.
    I found it a hoot. But then my son Jack committed suicide
    in 2015; I was so shocked that I lost the use of my legs for almost a month – and I was unable to eat
    properly for around three months. In that year, I lost around a third of my body weight.

    Julie Burchill in 1995.  She says there is ‘something so
    pitiful about the deaths of cerebral women in pursuit of beauty’

    The following year, when I started to recover, I was amazed to see how
    much younger I looked than I did before the most
    awful thing in my life happened. It was a contradiction that amazed and appalled me in equal measure.

    When I was 57, the Evening Standard offered to send me to the famous Dr Michael Prager (‘Where do you suggest I inject you?

    You have no frown lines’). I was hooked. 

    For the next four years I spent thousands of pounds
    on fillers and Botox – the nauseatingly named ‘tweakments’ that we always
    do ‘for ourselves’ so that we can look ‘rested.’

    Then came lockdown. When I emerged from it, I found that I hadn’t
    missed being ‘freshened up’. Instead, I felt freed up. I’ve read
    many middle-aged women – not even old ones, like me – testifying to how ‘traumatic’
    it is to be ‘invisible’; they mean to strangers, in public places.

    I find it a relief. Strange men started following me in the street when I was
    12 – I’ve had enough attention. Women, by the time they lose their looks, will have had all the sex they wanted and perhaps some they

    Of course, I understand that if your looks are your livelihood then the desire to preserve them becomes the most important thing in your life.
    But so many averagely attractive women appear to believe that they can keep their appeal market-fresh into middle and even old age.

    I’ve had friends in their 60s saying before yet another cosmetic
    procedure that they’re going to be in ‘the best shape of my life’
    in order to bag a rich man. None of them has managed it yet,
    as a rich man can take his pick of a far younger and better selection of lazy, parasitic females,
    if that’s his thing. It’s simply delusion.

    Of course, I don’t crave the old days when women were considered old at 40 – but neither do I wish to wear a new straitjacket
    which insists that women (or men) must be ‘hot’ at 60, 70, 80
    and beyond. Surely this is called gerontophilia?

    The writer, pictured today, says she hasn’t had fillers in  years
    and ‘won’t be getting her crumbling teeth done’

    I’m aware that I haven’t quite gone all the way towards completely losing interest in what
    I look like – I still put on a faceful of make-up every morning,
    have my hair dyed every month and over the past year I’ve gone from
    a size 20 to a size 16 due to experiments with slimming pills.

    The latter can be rationalised by saying that fatness in old age
    means extra pressure on weakening joints.

    Hair and make-up, however, don’t have any health-giving perks,
    and are obviously matters of sheer vanity. In defence of this duplicity,
    I’d say that Rome didn’t decay in a day – I’m having a ‘managed
    decline’. But I haven’t had fillers in years, and I won’t
    be getting my crumbling teeth done – when they’re gone, they’re gone.

    I haven’t had fillers in years and I won’t be getting my crumbling
    teeth done

    There’s something so pitiful about the deaths of cerebral women in pursuit of beauty: Professor Donda West, academic and mother of Kanye,
    dying at the age of 58 from complications following a ‘tummy tuck’, and the brilliant
    novelist Olivia Goldsmith, dying at 55 during
    a facelift.

    When we attempt to preserve our looks – whether by liposuction or lipstick – we
    are hoping to defy the ageing process and ultimately, beneath all the wellness
    noise, postpone the moment of our death. How weird
    if vanity hastens it! Sure, a bit of Botox never killed anyone – but the kind of cosmetic intervention it takes to make a
    long-term difference can do just that.

    If I google quotes by me about beauty, an excellent one pops up: ‘Youth and beauty are meant to be fuel, to be burned
    in pursuit of pleasure, and not fruit to be pickled in anticipation of
    some future famine.’

    But even better is what David Bowie said: ‘Ageing
    is an extraordinary process whereby you become the person you always should have been.’ Once I was beautiful – now I’m not.
    What’s left is the real me – at last.
