Hi there,

Since version 1.22.2 it seems that the mailpit.svg file cannot be loaded when using a webroot.

Using v1.22.2 without a webroot:

services:
  mailpit:
    image: axllent/mailpit:v1.22.2
    ports:
      - '8025:8025'

$ curl http://127.0.0.1:8025/mailpit.svg
<?xml version="1.0" encoding="UTF-8" standalone="no"?>
<svg
   width="500"
   height="460"
(...)

Using v1.22.2 with a webroot:

services:
  mailpit:
    image: axllent/mailpit:v1.22.2
    ports:
      - '8025:8025'
    environment:
      MP_WEBROOT: '/mailpit/'

$ curl http://127.0.0.1:8025/mailpit/mailpit.svg
File not found

Using v1.22.1 with a webroot:

services:
  mailpit:
    image: axllent/mailpit:v1.22.1
    ports:
      - '8025:8025'
    environment:
      MP_WEBROOT: '/mailpit/'

$ curl http://127.0.0.1:8025/mailpit/mailpit.svg
<?xml version="1.0" encoding="UTF-8" standalone="no"?>
<svg
   width="500"
   height="460"
(...)

I was seeing this as well when using the binary. Installed via the installer on Ubuntu and also generated the binary from the go code using the guide and same result.

Sounds like a bug. Thanks for reporting, I'll look into this soon.

I found the issue, which was caused in this case by the fact that both your webroot and the filename start with "mailpit"... It was "trimming" /mailpit off the virtual path to the file, however it did it multiple times, so /mailpit/mailpit.svg became just .svg 🤦

I have pushed a fix for this, however it hasn't yet been released as I try not release new versions too often (package maintainers get grumpy when I create extra work for them). Is this bug affecting just you, or is it impacting a wider audience (part of a larger Mailpit implementation)?

Just a heads up I was seeing the same issue with web root set to mail. Not sure if the fix will work for that case as well. The app is still fully usable just an annoying 404.

Yes, /mail/mailpit.svg would have resulted in pit.svg. I can confirm that this is solved in the bugfix I pushed. My question (to you both) is how big is the impact of this bug for you? If it affects a larger audience then I can release a new version now, otherwise I will wait a couple more days (weekend).

It can wait, don't worry :)
