Investigate correctness of line "delivery_method :@via, options"

[guyboertje]

I would have thought this version is more correct:

delivery_method @via.to_sym, options

[jstoja]

It's correct since there is a string to symbol conversion in the mailing library:

case method.is_a?(String) ? method.to_sym : method
