I totally agree! You guessed correctly, this home service was living
inside `(bioneland home services msmtp)`, so the naming seemed to make
sense at the time, but not any more!
Thanks again for your time and help!

Place this after '(define-configuration mstmp-account ...)'. You might want to place this block
before '(define-configuration msmtp-configuration ...)'.

You should preserve the @c lines from configuration->documentation to make it clear that
the block of text was generated.

You should export the accessors for the fields.
You can use this snippet within 'guix repl' to automate the typing for you:
--8<---------------cut here---------------start------------->8---
(define (helper-configuration-exports fields)
(map
(lambda (s)
(let* ((f (compose object->string configuration-field-getter))
(g (compose cadr string-tokenize))
(s* ((compose g f) s)))
(string->symbol (substring s* 1 (string-contains s* "-procedure")))))
fields))
(define (helper-formatted-exports fields)
(format #t "~{~a~%~}" (helper-configuration-exports fields)))
--8<---------------cut here---------------end--------------->8---
Example usage:
--8<---------------cut here---------------start------------->8---
;; paste snippet above into repl
scheme@(guix-user)> ,m (gnu services audio)
scheme@(gnu services audio)> (helper-formatted-exports mpd-configuration-fields)

You don't have to perform the maybe-value-set? checks, it is automatically done for you.
The only cases where this isn't true is if you explicitly override the serializer in
define-configuration. [2]

Duplicated?

This doesn't do anything and since it's a cosmetic change I'd just ignore it, since
the file is managed with guix anyways.

Instead of defining a raw-configuration-string? predicate, simply use string?
and set the serializer to '(serializer my-custom-string-serializer)' or '(serializer (lambda ...))'. [1]
> + (prefix configuration-))
These are poor prefix choices for a module named (gnu home services mail).
If it were (gnu home services msmtp) or (gnu home services mail msmtp) it would be acceptable
but a module named (gnu home services mail) is expected to eventually contain multiple services that
have to co-exist. These prefixes are too non-specific and confusion prone for such circumstances.
I'd set this to (prefix msmtp-configuration-). (the same logic applies to the remaining (prefix ...) lines)

You might want to separate each field with a space to make things easier to read but this is optional.

Hi Guix,
It's my first time 1) submitting a patch for a home service and
2) editing a `.texi` file, so please be understanding and…
pay special attention! :-)
Be aware that the code contains two FIXMEs:
- one that I don't know how to solve
```
+ ;; FIXME `In procedure every: Wrong type argument: #<syntax-transformer msmtp-account?>`
+ ;(every msmtp-account? lst))
```
- one that is a cosmetic change, and probabliy doesn't need fixing
```
+ ; FIXME Begin each line inside an account section with a space.
+ #~(string-append #$(serialize-configuration value msmtp-configuration-fields)))
```
And the documentation could probably be more detailed!
This being said… thanks for reading!
