Hi,
I am trying to send multiple header values. In a regular actionMailer I can use
headers['X-Header-Tag'] = ['tag1']
headers['X-Header-Tag'] = ['tag2']
Since wupee is doing a merge of headers as a hash, this is not possible.
Mail::Header can be passed as an object from wupee, but there the serialization is not allowing that.
also, the mailer method is expecting a hash
