Anvil-app-server noob questions

Anvil Q&A
11

Still cannot get the SMTP settings to work. but I now get the following error:

  2020-06-02 19:04:21,500 [ERROR anvil.app-server.run] Error report from client code:
  AnvilWrappedError: Invalid Addresses
  Traceback:
      <rpc>:0

  anvil-services/anvil/users.py:63

  anvil-services/anvil/users.py:469

  anvil-services/anvil/users.py:469

  app/CC_Test/Form1/__init__.py:15

But I believe I have might have found some answers by looking into code I don’t entirely understand. And on that basis please excuse me if I’m talking complete rubbish!

  1. smtp-encryption: option will accept the following values “ssl” or “starttls”.

    From email.clj line 227:

    (defn smtp-send [{:keys [host port user pass encryption] :as _smtp-config}
    {:keys [from-address from-name to cc bcc subject text html attachments inline-
    attachments in-reply-to references app-id] :as _message}]

    (when-not host
    (throw+ {:anvil/server-error “No SMTP server has been configured for this app”}))

    (let [session (Session/getInstance (make-props (merge {“mail.smtp.starttls.enable” (if (contains? #
    {“ssl” “starttls”} encryption) “true” “false”)}
    (when (= encryption “starttls”)
    {“mail.smtp.starttls.required” “true”}))))

  2. It appears that the smtp email “from account” might be hard coded to “accounts” which would make the “Invalid Addresses” error make sense as it is not a valid user on my email host.

From core.clj Line 232:

(defn send-email! [to subject text]
  (if (get-in @util/*session-state* [:users :test-email-divert])
    (swap! util/*session-state* update-in [:users :test-email-divert] concat [{:to to, :subject subject, :text text}])
    (binding [email/*use-quota* false
              email/*require-service-config* false]
      (email/send! {:from_name    (if (app-data/abuse-caution? util/*session-state* util/*app-id*)
                                    "Accounts"
                                    (str (:name util/*app*) " Accounts"))
                    :from_address "accounts"
                    :to           to
                    :subject      subject
                    :text         text}))))

Can someone check if I am understanding the code correctly and if my conclusion is correct.
