Former Tyner Elementary Teacher Travis D. Truett will spend 30 months behind bars.
Truett was arrested in 2004 for allegedly sending obscene e-emails and asking a student to meet him after school for sex.
Truett was sentenced in 2005, but appealed his sentencing.
His lawyer argued he should receive less jail time because he did not physically abuse the student.
Truett will have to serve at least 85 percent of his new sentence.
