ReplyTo Property
A mail address to which to reply (optional).
Syntax
public String getReplyTo(); public void setReplyTo(String replyTo);
Remarks
If this property contains a non-empty string, a Reply-To SMTP header is created for the message. This header shows the address to use for replies (useful if this address is different from the one in From).
If the resulting header is longer than MaxHeaderLength, then it is folded according to RFC 822 specifications.
Default Value
""
