There are three open pull requests adding this functionality:
(The patch here is identical to #26, so I just closed this one.)
Meanwhile, the most recent commit to the upstream repository was in
May 2019: that was the commit that first added `sendgmail`.
This commit adjusts Guix's `sendgmail`, following Postel's advice,
to make the command "liberal in its receiving behavior" (RFC 760):
it always accepts email addresses with any domain name, as in #26,
and it accepts (and ignores) the `-gsuite` flag used in #17.
* gnu/packages/patches/sendgmail-remove-domain-restriction.patch:
New file. This is the patch from #26.
* gnu/packages/patches/sendgmail-accept-ignored-gsuite-flag.patch:
New file, based on #17.
* gnu/local.mk (dist_patch_DATA): Add the new patches.
* gnu/packages/mail.scm (sendgmail)[source]: Apply the new patches.
Increment the "revision" argument to `git-version` from 0 to 1.

In case you are asking, "What does it mean for send*G*mail to support
non-`@gmail.com` email addresses?", here's some more context. As part of the
product variously known as Google Apps for Your Domain, GSuite, and, most
recently, Google Workspace, Google offers email hosting for arbitrary domains
(e.g. for work or schol, or from the "legacy free [gratis] edition"). The
Gmail API works for all of these domains, but the upstream version of the
`sendgmail` command checks that the email address passed as `-sender=` ends
with "@gmail.com".
The first fork to remove this limitation seems to have
by Flameeyes (Diego Elio Pettenò), which added an optional `-gsuite` flag to
disable the check, and thereby enable alternate domains. This approach has a
number of nice features. (I tried it for a while, and I've sent patches to
Guix with this fork.) In particular, by making alternative domains opt-in, it
preserves the nice error message for people who have merely made a typo.
The main disadvantage is that, in the time since the pull request was opened,
the product has been renamed, so it seems unlikely that the `-gsuite` flag
will be merged upstream. The history of this product's name also suggests that
a `-googleworkspace` flag might suffer the same fate eventually.
A second approach was taken by Tamas K Lengyel
the "@gmail.com" check altogether. On the other hand, this fork's `sendgmail`
fails with a usage note if it is passed a `-gsuite` flag.
(Later, I came up with exactly the same patch; I only realized after I
wasn't the first to want this feature.)
Usually I want to err on the side of validation, but I've come to think that
being permissive is the right trade-off in this case. The usual way of using
`sendgmail` is as a backend to `git send-email`, and, in that case, you aren't
supplying `-sender=` interactively: you'll set it up once with `git config`
when you get your API token, and then you'll forget about it until you set up
a new machine (or accidently remove the root that was protecting your command
from `guix gc` ...). Ultimately, the standard for whether a `-sender=` is
valid is whether the server you're talking to will accept it. If the server's
error message does turn out to be slightly less good, people who are using
`git send-email` seem likely to be able to cope.
In that spirit, this commit applies Tamas's patch, but also adds another patch
to gracefully accept and ignore the `-gsuite` flag from Flameeyes's fork. If
your configuration or script worked with any of these `sendgmail` forks, it
should also work with the revised Guix package.
P.S. I've put the two patches to `sendgmail` in a Git repository at
to make it easier to see the changes in context.
