Haven't had a chance to test it yet.

Thanks for chasing this!

The actual source of the problem is in DDEV, and apparently it's been there since before the mailpit change. See

https://github.com/ddev/ddev/blob/38a31a0c5f219b9258f6a8b0dd15841d26b904c6/pkg/ddevapp/ddevapp.go#L2064-L2078

OK. Not sure what changes you would like here though.

[rfay]

There is no way to change it here, as it needs to be changed in DDEV.

But I'm not sure why it needs to be changed. Is it ddev mailpit that needs to be changed? What is the goal?

[tyler36]

Consistency, mostly.

EG. Xdebug port:

• FIle lists 9000 as xdebug port, but xdebug is on 9003. So this is confusing.
• If it doesn't matter (ie, we don't use it), lets delete the entry so there's less maintainance.

[rfay]

Xdebug has been on 9003 for several years, since before gitpod support. I'm wondering how it got that?

If you can live with mailpit listening on 8027, it's OK there. People shouldn't have to know where these ports are.

Sorry, I got confused between your two PRs
