msmtp

msmtp is an open source SMTP client that can be used with Mutt and other MUAs.

To use msmtp with your MUA, just create a configuration file with your email account(s) and tell MUA to call msmtp.

What is new in this release:

• This release fixes a bug that prevented consecutive Bcc headers from being removed properly. It is recommended to upgrade.

What is new in version 1.4.31:

• This release includes a new version of the msmtpq script and fixes building the documentation with texinfo version 5.x.

What is new in version 1.4.30:

• This version fixes a bug introduced in 1.4.29 that broke the --read-recipients option when --read-envelope-from was used.

What is new in version 1.4.28:

• This release fixes a few minor problems.

What is new in version 1.4.27:

• This version fixes a problem with configurations that use OpenSSL and at the same time do not use GNU SASL. (If you use a different configuration, there's no reason to upgrade.)

What is new in version 1.4.26:

• This release updates the msmtpq script.
• To use the new version of the script, you need to remove the old msmtpQ symlink, change msmtpQ to msmtpq in your MUA config, and use msmtp-queue for queue management.

What is new in version 1.4.23:

• This release fixes SCRAM-SHA-1 authentication via GNU SASL.
• If you use a version of msmtp that supports SCRAM-SHA-1 authentication via libgsasl (see the output of msmtp --version), then an update is recommended.

What is new in version 1.4.22:

• This release adds a passwordeval command that allows to set the password to the output of a program invocation.

What is new in version 1.4.21:

• This minor update mainly fixes build problems with newer OpenSSL versions and with disabled TLS/SSL support.

What is new in version 1.4.20:

• This release adds support for authentication mechanism SCRAM-SHA-1 via GNU SASL. The new command tls_fingerprint allows one to trust one particular TLS certificate, in case tls_trust_file cannot be used for some reason. The new script msmtp-gnome-tool.py manages Gnome Keyring passwords for msmtp.

Requirements:

• If you want TLS/SSL support, you need either GnuTLS (>=1.2.0) or OpenSSL (>=0.9.6).
• You can optionally use GNU SASL if you need more authentication methods than PLAIN, LOGIN, CRAM-MD5, and EXTERNAL; for example GSSAPI, DIGEST-MD5 or NTLM.
