3.20.3 mailutils info

The mailutils info command displays information about Mailutils compile-time configuration. In normal form its output lists a single configuration flag per line, e.g.:

$ mailutils info
VERSION=2.99.93
SYSCONFDIR=/etc
MAILSPOOLDIR=/var/mail/
SCHEME=mbox
LOG_FACILITY=mail
IPV6
USE_LIBPAM
HAVE_LIBLTDL
WITH_GDBM
WITH_GNUTLS
WITH_GSASL

A configuration flag can consist either of a single word, indicating that a particular capability has been enabled at compile time, or of a keyword/value pair delimited by an equal sign, which indicates a particular value used by default for that feature. For example, ‘IPV6’ means that Mailutils was compiled with support for IPv6, whereas ‘SYSCONFDIR=/etc’ means that the default place for configuration files is in /etc directory.

Such short output is convenient for using mailutils info in scripts to decide whether it is possible to use a given feature. To assist human users, the --verbose (-v) option is provided. It prints a short description next to each flag:
