[Bug]: (apprise) E-mail notifications broken to email servers by IP address

[kroese]

Since very recently the e-mail (SMTP) notifications do not function anymore. I think this was introduced somewhere between v0.45.18 and v0.45.20.

Also I do not see any button anymore to send a test notification, making the problem harder to debug (but that might be a separate bug).

The error I get is:

SENDING - null

raise SMTPServerDisconnected('please run connect() first')

The notification URL is:

mailto://10.0.0.195:2225/?to=alerts@example.com&from=sender@example.com

This a local postfix server without any authentication, and it doesnt even receive any incoming request.

This configuration has always worked and I didnt make any changes (except for updating the container) when it stopped working.

From the log this looks suspicous:

E-Mail URL: mailto://:2225/alerts%40example.com?format=html&overflow=upstream&rto=4.0&cto=15&verify=yes&from=sender%40example.com

It seems like it stripped the hostname from the URL, which would explain why it cannot connect.

Version v0.45.20

To Reproduce

Create a notification URL like this:

mailto://10.0.0.195:2225/?to=alerts@example.com&from=sender@example.com

It fails to send any mail and it also doesnt show any test button.

Expected behavior

Emails that get delivered

[dgtlmoon]

please try it first from the command line

echo hello|apprise mailto://10.0.0.195:2225/?to=alerts@example.com&from=sender@example.com

it is not a bug with changedetection but rather with apprise, does it work from the CLI?

and tell me the version of apprise installed pip3 list

[kroese]

Its version 1.7.6 and when I execute that command I get:

ERROR: There are no service(s) to notify

but the Loaded E-Mail URL contains the IP like expected, while in the Change Notification log the IP is stripped from that line.

[dgtlmoon]

So its a problem in 1.7.6 of apprise then...

pip3 install apprise==1.7.5

$ ls|apprise "mailto://10.0.0.195:2225/?to=alerts@example.com&from=sender@example.com" -v

@kroese please can you make an issue over at caronc/apprise? this is not our fault here

[dgtlmoon]

@kroese please make an issue at https://github.com/caronc/apprise and link this issue in the issue comment

[kroese]

Okay, thanks! I reported it and will take it further with them.

On a sidenote, do you have any idea why I dont see the button to test notifications in v0.45.20? I know you recently changed something in that area of the code, but I cant find it anywhere.
