Email wont send due to spam filter

Trying to send emails to my tennis club committee and the emails won't send with the following message:

552 5.7.0 SPAM Content Found (VM603) RYWihVI3VkdLIRYWihzPnV

Have checked outgoing SMTP settings and they work OK. Test emails to my gmail address OK so must be something in this message that is causing spam filter to reject it (having read other similar threads). It's just wording with no codes or URLs so I can't see why its doing this.

Can you help please.

Thanks

Jim

Re: Email wont send due to spam filter

You are possibly suffering from a false positive. Most spam filters use some sort of “dictionary of dodgy terms” when scanning emails for spam. Unfortunately they can sometimes come up with positive results arising from hidden words-within-a-word-or-phrases.

Examples – Scun-thorpe            Spe-cialis-t           new-balls-please (we are talking tennis here)

If you have the time or inclination, a simple way to check for such things is to send yourself 2 emails each one containing half of the original text. Hopefully, only one will fail the spam test and you can repeat the process until you identify what is causing the problem. If both halves fail you have the same term in both halves, so you repeat the sub-division until you are left with just one block of text which fails. I trust that you haven’t put anything new in your email signature recently.

FYI: Webmail allows spam content to be sent between Virgin Media domains with delivery to the recipient's Spam folder whereas with an email client the spam content warning is displayed; for expediency consider using the latter to troubleshoot the false positive.

Re: Email wont send due to spam filter

I tried that but both halves of the email sent okay which is curious. Also the full emails sent via webmail as opposed to my PC based email program.

I couldn't see anything in the wording that might have triggered it.

Many thanks

Jim

Re: Email wont send due to spam filter

Glad to hear your emails are now passing the Spam test. Your successful emails probably went through different (updated) spam filters second time through. See below for some further thoughts on the issue.

All major email providers wage a constant daily battle with the detection and prevention of Spam. Most employ specialist help – as VM does. I would’t like to say who is winning the battle at the moment. Note that this site - https://www.statista.com/statistics/420391/spam-email-traffic-share/ - estimates that of the 281 billion messages per day input to the global email system in 2018, 57% were Spam. That is indicative of the problem scale. It’s big – as well as being complex. So, changes to the defences routinely take place at least on a daily basis (or sometimes more frequently in response to any new deluge of Spam). This rate of change is such that a few mistakes in the data-sets are almost inevitable in the rush to update the defences, giving rise to things like “false positives” - which I suspect was what happened in your case. Such false positives are usually detected and corrected in an update inside a day or two – unless a lot of people are adversely affected and complain appropriately – in which case it might be quicker. It is not easy.
