[dependabot[bot]]

Bumps mail from 2.7.1 to 2.8.1.

Changelog

Sourced from mail's changelog.

== Version 2.8.1 (unreleased)

Bug Fixes:

• Regression: sendmail accepts string :arguments (@​sebbASF)
• Regression: accept enable_starttls_auto: false @​ahorek

== Version 2.8.0.1 (12-Jan-2023)

Bug fixes:

• Regression: incorrect permissions for some files (mikel)

== Version 2.8.0 (3-Dec-2022)

Breaking changes:

• Add Ruby 3.1 support (deivid-rodriguez, voxik, eregon)
• Drop support for Ruby < 2.5 (deivid-rodriguez, voxik)
• Message#without_attachments! now deletes nested attachments. (TylerRick)
• Sendmail and exim delivery now raise DeliveryError when the command exits with a nonzero exitstatus. (benmmurphy, CoolElvis)
• Sendmail and exim delivery :arguments option must be an array of string args. (benmmurphy)
• Passing unparsed headers to Mail::Field.new is no longer supported. Use Mail::Field.parse. (jeremy)
• Removed long-deprecated features: Message#register_for_delivery_notification, #has_transfer_encoding?, #add_transfer_encoding, #transfer_encoding, #message_content_type, #mime_parameters, #encode!, and Part#inline_content_id. (jeremy)

Deprecations:

• Deprecates Mail::CheckDeliveryParams in favour of Mail::SmtpEnvelope

Compatibility:

• Handle a wide variety of non-RFC Message-ID formats. (peterkovacs)
• Normalize Quoted-Printable line endings for text content. (jeremy)
• Gracefully parse invalid dates in Date and Received headers. (okkez)
• Converting to multipart moves Content-* headers to the new part. (kirikak2)
• Multipart Content-Type no longer includes a needless charset param. (kirikak2)
• Replies prefix subject with "Re: " instead of "RE: " per 5322 3.6.5. (mashedcode)
• Gracefully handle multiple, possibly-invalid headers for what should be singular fields. (rosa)
• SMTP delivery with enable_tls/starttls/starttls_auto: false now disables these options, since starttls is now :auto by default in upstream net-smtp. (jeremy)

Features:

• Message#inspect_structure and PartsList#inspect_structure pretty-print the hierarchy of message parts. (TylerRick)
• an_attachment_with_mime_type matcher added to match attachments by mime type

Bug Fixes:

• Regression: Preserve message-level charset when adding parts (related to Rails ActionMailer) @​shields
• Regression: Adding a part should not reset the mail's charset to nil @​railsbob

# We need to freeze the mail gem version as the recently released 2.8.0 triggers an exception
# We will need to check if it's fixed when we migrate to Ruby 3.0/3.1
# See : https://github.com/DMPRoadmap/roadmap/issues/3254
gem 'mail', '2.7.1'

The above code exists in our Gemfile, as well as the current Gemfile of DMPRoadmap. We need to test whether or not this gem can be unfrozen.
