A postman sent parcels of dog excrement to Avon and Somerset police in a row over a damaged umbrella stand.
Franco Ippolito, 54, began the campaign claiming officers damaged the stand in a search of his home in Southville.
When he was refused compensation he sent parcels to the officers involved, Bristol Magistrates' Court heard.
He was given a 12-month community order after admitting four counts of sending an indecent or offending article through the post.
He was also ordered to pay £55 costs.
Det Con Carol Newton, who led the investigation into the packages, said: "Ippolito's son was arrested over an unconnected matter and a search was conducted of the house in April last year.
Caught through DNA
"He put in this complaint because of his umbrella stand, but compensation was not paid because he had refused to let the officers in so they had to force their way in.
"The complaints and discipline office then received the first two parcels."
The packages were sent to force headquarters in Portishead and New Bridewell police station.
Ms Newton said the packages were opened by civilian staff, who were "upset" by the stinking contents.
"One that came to the CID office sat on the admin desk for a while because the officer it was addressed to was on annual leave. It got gradually smellier so it was decided to open it," she said.
Police worked out the only link between the two officers who received parcels and the complaints team was Ippolito's claim over his damaged umbrella stand.
His DNA was discovered on postage stamps used on the packages and his fingerprints were found on adhesive tape used to wrap them.
