HMRC email flagged up as spam

[#1]

Just a heads up note that an email to me from noreply@hmrc.gov.uk this morning was tagged as spam by Plusnet's systems.
It was actually a confirmation notification from HMRC of satisfactory receipt of my online SA tax return as indeed it said in the subject line so all perfectly legit and expected.

Probably because there have been LOADS of mails from "hmrc" saying we all have tax refunds.
