chasquid v1.15.1

[Alberto Bertogli]

Hi!

chasquid v1.15.1 has been released.

chasquid is an SMTP (email) server with a focus on simplicity, security,
and ease of operation. It's written in Go, and is open source under the
Apache license 2.0.

See https://blitiri.com.ar/p/chasquid/ for more information.


There is only one change in this release: Disable TLS session tickets to
work around Microsoft problems.

Microsoft SMTP servers have a bug that prevents them from successfully
establishing a TLS connection against modern Go TLS servers, and some
OpenSSL versions. It also doesn't fall back to plain-text, so this has
been causing deliverablity issues.

The problem started by the end of 2024 and it's still not fixed.

Unfortunately, because they're quite a big provider and are not fixing
their problem, it is worth to do a server-side workaround.

See https://github.com/golang/go/issues/70232 and
https://github.com/albertito/chasquid/issues/64 for more details.

Thank you!
Alberto
