riemann email exception with SMTP

问题

I was able to set up riemann with SMTP. Riemann appears to send the email out when the condition is met but I observe an exception (copied below) - any insight on how to troubleshoot/fix this will be appreciated.

Config

    (def email (mailer {:host "xxx.xxx.xxx.xxx"
                        :port "xxxx"
                        :user "user@somewhere.com"
                        :pass "user12345"
                        :from "user@somewhere.com"}))

(streams
 (where (and (service #"^riemann netty execution-handler"))
        (email "user@somewhere.com")))

Error:

The issue was resolved by specifying the port number as a number (without the inverted commas).

Config

 (def email (mailer {:host "xxx.xxx.xxx.xxx"
                        :port xxxx
                        :user "user@somewhere.com"
                        :pass "user12345"
                        :from "user@somewhere.com"}))

(streams
 (where (and (service #"^riemann netty execution-handler"))
        (email "user@somewhere.com")))
