In Go 1.25.11/1.26.4, net/textproto error formatting was changed, and
now the message is quoted. This is to protect from general string
injections.
See https://go-review.googlesource.com/c/go/+/778182 and
ec1c380418ec6a0da28d4519872e2b81ba9152ba.
After this change, the error strings from net/textproto (and net/smtp
which uses it) now include quotes.
For chasquid, the only user-observable change in the server is that the
errors included in the DSN messages are now quoted, which should not be
a problem.
However, some of the tests which validate error strings need to be
adjusted.
The patch also updates go.mod to set the Go version to match this new
minimum.
The mda-lmtp tests are missing a file in the repository, which causes the
test to fail. This went unnoticed because they are not included in the
automated test suite, which will be fixed in a follow-up patch.
This patch adds the mising test file, with a harder to miss name.
mda-lmtp is a very basic MDA that uses LMTP to do the mail delivery.
It takes command line arguments similar to maildrop or procmail, reads an
email via standard input, and sends it over the given LMTP server.
Supports connecting to LMTP servers over UNIX sockets and TCP.
Since chasquid does not support direct LMTP local delivery, this can be
used as a workaround instead.
Example of use:
$ mda-lmtp --addr localhost:1234 -f juan@casa -d jose < email
