Problem sending email with one specific url

[#1]

I use Outlook on a PC and iOS via my PN email account.

Today, I tried to send an email with a link to a You Tube clip but iOS refused and then so did Outlook! I got this message via Outlook:-

"...message rejected due to spam or virus. If you believe this is in error please login to your portal or contact your ISP support team."

Here's the url: https://www.youtube.com/watch?v=_Q-scxybnp0

I can only think that there's PN software detecting something it thinks, wrongly, is dubious about this link.

PN: please do whatever is necessary to allow this link. (Too late for me as I sent it via Gmail.)

The forum notification for the opening post ended up in my spam folder, presumably due to it including that URL However no obvious reason for classifying the URL as spam was apparent when I viewed it.

t reported it as not spam.using webmail.

Should be sorted now.

There have been numerous threads recently of reported 'can't send email due to spam or virus' I suffered from it during March. 

Have PN up their filter settings or something?

Thanks all and BobP: it does appear to be OK now.

Was it PN anti virus software, Bob?

It's the outbound spam filtering on our SMTP servers. For one reason or another, some of the heuristics we rely on considered messages containing that specific YouTube URL to be spam. This could be for a number of reasons e.g. somebody sending a load of unsolicited newsletters to people containing a link to the video.

Thanks, Bob.
