Spam levels have reached a two and a half year low after some of the largest botnets were taken out of action.
The latest monthly survey of the state of the spam market from Symantec revealed that the tide has been turning against the inbox plague since the start of the year.
Back in January the channel started to notice a drop in spam levels with some commenting that the spammers were taking a holiday.
But with the Rustock and Bagle botnets being taken out of circulation the impact has taken spam levels down to their lowest since November 2008.
But Paul Wood, senior intelligence analyst at Symantec.cloud, urged resellers to keep their customers on guard.
"Despite the decrease in botnet spam this month, they should still be considered a dangerous force on the internet," he said.
"Spam remains a huge problem and spam levels continue to be unpredictable," he added.
The most common form of spam is on a pharmaceutical theme with spammers using various techniques, including fake brands, to try and get users to click on the emails.
Other highlights from the Symantec monthly security survey included identifying a trend for public sector organisations to be victims of phising attacks.
