That article is just the opinion of Richard Mawrey QC.

Here is the Electoral Fraud Review report from the Electoral Commission in 2014. Mawrey seems to strongly disagree with the findings of the report.

The Electoral Fraud Review report concludes that banning postal voting (in specific areas or altogether) would be a "disproportionate" response to allegations of voter fraud.

It also quite explicitly states that limiting postal votes would reduce the risk of voter fraud (p34) and acknowledges some evidence of systematic voter fraud in some regions of the UK exists.
