Send mail with attachment and signature via AppleScript in OS X

gistfile1.applescript

tell application "Mail"

	set theSubject to "Subject" -- the subject
	set theContent to "Content" -- the content
	set theAddress to "xxx@163.com" -- the receiver 
	set theSignatureName to "signature_name"-- the signature name
	set theAttachmentFile to "Macintosh HD:Users:moligaloo:Downloads:attachment.pdf" -- the attachment path

	set msg to make new outgoing message with properties {subject: theSubject, content: theContent, visible:true}

	tell msg to make new to recipient at end of every to recipient with properties {address:theAddress}
	tell msg to make new attachment with properties {file name:theAttachmentFile as alias}

	set message signature of msg to signature theSignatureName

	send msg
end tell

This works for me except the signature part... I am experimenting on a fix but having trouble

Likewise all works for me excluding the signature, which becomes active and then returns to none..

delay 1 is needed to finish attaching the file. BTW, signature does not work for me also.

@Quantizen where does delay 1 go?

@Quantizen nevermind, I got it! Just put it before the send command and worked like a charm. Been searching and searching for that!

Definitely needed the delay command. I used a delay 5 just in case things are going slow. Put it right before send command. I skipped using the signature and added it to the content itself.
