Duplicate emails using MIME::Lite with smtp

sandor.farkas has asked for the wisdom of the Perl Monks concerning the following question:

Hello,

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!
Sandor

The behaviour described is precisely what should happen. If you do not want a user to receive two copies, don't send them two copies in the first place. You could use something like List::MoreUtils to deduplicate your recipient lists in advance.	[reply]

Thank you, I will filter the recipients then.	[reply]
