Postma was signed by Aston Villa on 14 May 2002 for 1.5 million pounds, upon Peter Schmeichel's transfer to Manchester City. Postma's debut came as a substitute in a 0–1 defeat at Southampton on October 21, following the dismissal of Peter Enckelman.
After newly appointed Villa manager David O'Leary purchased Danish keeper Thomas Sørensen, Postma became the club's second choice goalkeeper at the club. He made two appearances in the 2003–04 season and three in 2004–05.
Towards the end of his time at Villa, Postma was linked with transfers to several European clubs before going on loan to Wolverhampton Wanderers at the start of the 2005-06 season. In January 2006, he signed a contract to remain at Wolves until the end of the season. It was announced on 5 May that year that he would leave Wolves in the summer, and he returned to the Eredivisie with ADO Den Haag .
In August 2008, Postma rejoined former club De Graafschap on a six-month contract.
In 2006, Postma became embroiled in a sex scandal when his ex-girlfriend posted a pornographic video featuring his partner penetrating him with a strapon on YouTube. The Mirror reported that Postma had "originally managed to keep the video secret by buying it when his ex tried to sell it on eBay."
