Bumps net-imap from 0.4.10 to 0.4.20.

Release notes

Sourced from net-imap's releases.

v0.4.20

What's Changed

🔒 Security

This release backports two features to prevent unbounded memory use: the response_handlers keyword argument to Net::IMAP.new so response handlers can be added before the server can send any responses (ruby/net-imap#427), and the max_response_size config attribute (ruby/net-imap#445, GHSA-j3g3-5qv5-52mj, CVE-2025-43857, reported by @​Masamuneee).

[!NOTE] The default max_response_size is nil (unlimited), to avoid backward compatibility issues with secure connections to trusted servers that are well-behaved. It can be configured more conservatively to guard against untrusted servers (for example, connecting to user-provided hostnames). It is the responsibility of net-imap users to configure their client appropriately for the server they are connecting to.

Known Issues

Fixed in v0.4.22: Ruby 3.0.0 through 3.0.2 on Mac OS crash when net/imap is required (ruby/net-imap#471).

[!IMPORTANT] This is fixed by Ruby 3.0.3, which was released 2021-11-24. Ruby 3.0.7 was released on 2024-04-23. Ruby 3.0 has reached its EOL.

If you are affected by ruby/net-imap#471, upgrading Ruby is much more important than upgrading net-imap!

OK, I won't notify you again about this release, but will get in touch when a new version is available. If you'd rather skip all updates until the next major or minor version, let me know by commenting @dependabot ignore this major version or @dependabot ignore this minor version. You can also ignore all major, minor, or patch releases for a dependency by adding an ignore condition with the desired update_types to your config file.

If you change your mind, just re-open this PR and I'll resolve any conflicts on it.
