+# Assuming the {send_from} is joe@example.com
+# Assuming the {login} is user1@example.com
+# Assuming the {password} is pass123

+
+# Notes (for above URL):
+# - Since no `to=` was specified above, the `from` address is notified
+# - mailtos:// defaults to starttls on 587; if you want to use port 465 (SSL)
+#   you would just need to add `mode=ssl` to the parameter of your URL.
+
+# Here is a more complicated example where you want to use `ssl` and a custom port

+# Assuming the {smtp_server} is mail.example.com
+# Assuming the {send_from} is joe@example.com
+# Assuming the {login} is user1@example.com
