Resend API key required even with custom SMTP

[ro78]

Describe the bug
Since a recent release, we can use an external (custom) SMTP instead of Resend.
But when I try to use it, it's still asks me to configure a Resend API key.

To Reproduce
Steps to reproduce the behavior:

1. Install pop on a clear host
2. Run the command pop --smtp.host localhost --smtp.port 25 --from [email protected]
3. See error

Expected behavior
Pop doesn't display any error related to Resend

I found that username & password is mandatory. I think it's better to accept using SMTP without them, as some hosts are trusted relays without any auth.

Any update on this?? still having the same issue.

Any update from me? No, I reported this bug and I don't have any update from the developer.

Looks like currently it's a feature, not a bug.
You can't set smtp credential via command line, you have to set them via environment variables.

That’s a bug.
You should be able to post though a local SMTP without authentication.

compare

$ export POP_SMTP_HOST=localhost
$ export POP_SMTP_PORT=25
$ pop

   ERROR   RESEND_API_KEY  environment variable is required.

   You can grab one at https://resend.com/api-keys

with:

$ export POP_SMTP_HOST=localhost
$ export POP_SMTP_PORT=25
$ export POP_SMTP_USERNAME=foo
$ export POP_SMTP_PASSWORD=bar
$ pop
                                       
 From foo                              
 To [email protected]                    
 Subject Hello!                        
                                       
 ┃ # Email                             
…

Anyway, you can work around that limitation by setting: a bogus POP_SMTP_USERNAME and a bogus POP_SMTP_PASSWORD and POP_SMTP_ENCRYPTION=none

$ export POP_SMTP_HOST=localhost
$ export POP_SMTP_PORT=25
$ export POP_SMTP_USERNAME=foo
$ export POP_SMTP_PASSWORD=bar
$ export POP_SMTP_ENCRYPTION=none
$ pop

(it works!)

Also, pop makes a(nother) very unwelcome assumption, for a TUI software: it forces the use of fully qualified From and To email addresses ([email protected]). From a "terminal" perspective, especially with POP_SMTP_HOST=localhost a user expects being able to send emails from & to local addresses:

$ pop
                                       
 From user1                              
 To user2                    
 Subject Hello!                        
                                       
 ┃ # Email                             
…

An email address of the form "user" is perfectly legitimate on the local system.
