I used this code and after finish I can´t delete the attached file, any idea?
(send-message {:host "smtp.gmail.com" :user usuario :pass senha :tls :yes :port 587} {:from usuario :to destino :subject "Reports" :body [{:type "text/html" :content (clojure.string/replace (slurp template) #"\$mes" mes)} {:type :inline :content (java.io.File. anexo) :content-type "application/pdf"}]})

Is this on Windows?

Yes, on Windows

I don't believe the JVM guarantees a timeline for GC. If you use a try/finally block to force the file to close, does that resolve the issue?

(BTW, Windows is the only modern operating system I know of where open files can't be unlinked; typically it's just a reference count decrement).

I tried this too:
( let [anexo (java.io.File. "file.pdf")] (send-message {:host "smtp.gmail.com" :user usuario :pass senha :tls :yes :port 587} {:from usuario :to destino :subject "Reports" :body [{:type "text/html" :content (clojure.string/replace (slurp template) #"\$mes" mes)} {:type :inline :content anexo :content-type "application/pdf"}]} (.close anexo)) , same result

So, I tried to rewrite it like:

(defn make-auth [user pass]
    (proxy (javax.mail.Authenticator) []
        (getPasswordAuthentication [] (PasswordAuthentication. user pass))))

(defn enviar-email-anexo [host porta usuario senha anexo destinatario]
    (let [prop (Properties.)
                _ (.put prop "mail.smtp.host" host) 
                _ (.put prop "mail.smtp.port" porta)
                _ (.put prop"mail.smtp.auth" true)
                _ (.put prop "mail.smtp.starttls.enable" true)
                _ (.put prop "mail.user" usuario)
                _ (.put prop "mail.password" senha)
                auth (make-auth usuario senha)
                sessao (Session/getInstance prop auth)
                mensagem (MimeMessage. sessao)
                messageBodyPart (MimeBodyPart.)
                multipart (MimeMultipart.)
                attachPart (MimeBodyPart.)
                ]
        (.setFrom mensagem (InternetAddress. usuario))
        (.setRecipient mensagem Message$RecipientType/TO (InternetAddress. destinatario))
        (.setSubject mensagem "Relatório de Service Desk")

        (.setContent messageBodyPart "<html><body>Hello</body></html>" "text/html")
        (.addBodyPart multipart messageBodyPart)

        (.attachFile attachPart anexo)
        (.addBodyPart multipart attachPart)

        (.setContent mensagem multipart)
        (Transport/send mensagem)
        ))

and it´s not blocking the file. So I think in some situation your code keep the file open.
