Following on redcardinal's post ....
If you can decipher the mail headers then you can report the spammer to either their ISP or their hosting company or both (depending on how the mails were sent)
By default most ISPs / hosts maintain abuse@ for spam reports.
If you are going to report spam please do so in a timely fashion and include samples with headers.
If the spammer is Irish you could contact the data privacy commissioner, but the reporting options are quite painful ie. you cannot simply email them and hope they will take action. You are expected to report via letter etc., which is a large burden - too much IMHO
Report spammers to DNS blacklists.
If a spammer or spammed domain gets reported and listed it can help both you and other users of DNS blacklists to block future emails from them.
You can get accounts to report spam on site such as SpamCop.net - Beware of cheap imitations and URIBL.COM - Realtime URI Blacklist
