I have an issue sending emails via MIME::Lite module. I have to set some header parameters (return-path and reply-to) therefore I have to use $msg->send('smtp', $SMTP_HOST);
If I understand right in this case the message now sent via Net::SMTP. Unfortunately it results that if an email address is included in both to and cc fields the message is delivered twice. I'm googling for a while now, but I can't figure out what is the reason behind. Can anyone please give me a hint on this?
Thank you in advance!
