Swaks 20240103.0

New features

• Added --cc and --bcc options
• Numerous TLS debugging and verification improvements
  • Debug output contains whether a client cert was requested and whether one was sent
  • Add new options --tls-verify-ca and --tls-verify-host to differentiate between types of certificate verification (--tls-verify does both)
  • Add --tls-target option to allow setting of hostname to be used in hostname verification. This is useful in some inet debugging situations and required to do hostname verification with --socket or --pipe
  • Add --tls-chain
  • Add --tls-get-peer-chain option (analogous to --tls-get-peer-cert)
  • Certificate debug now includes all client and peer certs, it a chain was used
  • Certificate debug now includes notAfter, commonName, and subjectAltName

Notable changes

• --output-file, --output-file-stderr, and --output-file-stdout now truncate the specified file if it already exists
• Documentation improvements
• Extensive test harness improvements
• Add new stop-point XCLIENT-HELO to address lack of specificity when mixing XCLIENT usage with the HELO stop-point
• Add new stop-point PROXY
• Use IO::Socket::IP by default. Will still use IO::Socket::INET/INET6 to cover transition, but this is deprecated and will be removed in the future
• TLS session debug information is now printed even if we decide not to continue the session (e.g. for failed verification)
• Previously-deprecated functionality to allow some options to be either a filename or a literal string has been removed. Using the @ sigil is now the only was to specify file contents
• Previously-deprecated -g option removed

Notable bugs fixed

• TLS certificate verification did not always work, it should now

Swaks 20201014.0

Notable bugs fixed

• Last release introduced a bug where Date: headers were localized, which is against RFC. Further, that localization then broke character rendering in some locales. A new fix for the original issue was put in place, which no longer localizes the Date: header and fixes the newly introduced rendering issue.
• Last release introduced a bug which prevented --protect-prompt from working. This is now fixed.

Swaks 20201010.0

New features

• Added .netrc support
• Added --tls-sni option
• Swaks is now available on CPAN as App::swaks
• Swaks will now print errors if deprecated functionality is used

Notable changes

• Automatic file detection is deprecated. Previously, if an argument to --data, --body, --attach-body, and --attach resolved to an openable file, the contents of that file would be used as the actual argument. Now the proper way to do this is to place @ in front of the argument to state explicitly that the argument contents are in a file.
• If any of the --xclient-* family of options (--xclient-name, --xclient-addr, etc) is provided more than once, only the last option provided will be used. See --xclient option if you need to simulate the previous behavior
• -g option is now deprecated
• Time::Local is no longer used and POSIX is now listed as a required module

Notable bugs fixed

• Fix for subtle issue related to environment variable options. Affected error handling for options which required args.
• Fix issue preventing XCLIENT and STARTTLS from working together properly
• Fix issue which could cause generated date header to oscillate on the day of DST transition

Swaks 20190914.0

New features

• Source is now available on github.com/jetmore/swaks
• Added --body-attach option to allow more granularity in setting body information
• Added 'data' and 'dot' as valid --drop-after-send and --drop-after arguments
• Added %NEWLINE% as a new --data token

Notable changes

• Options provided via environment variable are now sorted before processing to provide a deterministic processing order
• Option bundling is no longer enabled. This fixes several option processing oddities, like -foobar being interpreted as -f oobar
• If the arg to --data looks like a file but is not openable, error and exit instead of using it the file name as the raw data value
• Remove interactive prompts for --helo and --from when hostname cannot be determined internally, just error and exit instead. If the user was not expecting an interactive experience, don't start one
• Remove re-prompting for port when an invalid service name was supplied, just error and exit instead. If the user was not expecting an interactive experience, don't start one

Notable bugs fixed

• Handle malformed headers more gracefully in header replacement
• Fix bug causing the processing of options prefixed with the negating no- to work unreliably
• --version and --help should work even if they aren't the very first option
• -S is now a distinct option from -s, as documented
• Fix bug preventing the --option=arg option format from being unusable with --header and --attach* options
