* Automatic Dockerfile update by release process

* Describe environment variables for email config

New environment variables were introduced to enable users to configure
SMTP email forwarding. The variables were listed in the readme but not
described leaving users in the dark regarding the expected content of
the variables.

* Fix bulletpoint formatting

Instead of sub-bullets we present the explanation for email environment
variables as simple text instead.

* Push email env variable explanations to separate line

 The following parameters are now supported to set mail preferences:
 
-* `LSMB_MAIL_SMTPHOST`
-* `LSMB_MAIL_SMTPPORT`
-* `LSMB_MAIL_SMTPTLS`
-* `LSMB_MAIL_SMTPSENDER_HOSTNAME`
-* `LSMB_MAIL_SMTPUSER`
-* `LSMB_MAIL_SMTPPASS`
-* `LSMB_MAIL_SMTPAUTHMECH`
+* `LSMB_MAIL_SMTPHOST` \
+  The host name/IP-address of the SMTP server that will forward mail from
+  LedgerSMB to the outside world.
+* `LSMB_MAIL_SMTPPORT` \
+  The port that the SMTP server in `LSMB_MAIL_SMTPHOST` listens to.
+* `LSMB_MAIL_SMTPTLS` \
+  Can be one of `no` (default), `yes` or `raw`. `yes` indicates to use
+  STARTTLS over a regular SMTP connection; `raw`' indicates an SMTP connection
+  should be established over a TLS connection (a.k.a. smtps).
+* `LSMB_MAIL_SMTPSENDER_HOSTNAME` (optional) \
+  When set, used to identify the host when connecting to an SMTP server. When
+  not set, the host is queried for its host name.
+* `LSMB_MAIL_SMTPUSER` \
+  Username to authenticate to the SMTP host in `LSMB_MAIL_SMTPHOST`.
+* `LSMB_MAIL_SMTPPASS` \
+  Password to authenticate to the SMTP host in `LSMB_MAIL_SMTPHOST` with the
+  user in `LSMB_MAIL_SMTPUSER`.
+* `LSMB_MAIL_SMTPAUTHMECH` \
+  A space separated list of SASL mechanisms to be used for authentication of
+  the smtp connection with the SMTP server. Available mechanisms depend on
+  your installed environment, but the following mechanisms should be available
+  in all of them: `PLAIN` `LOGIN` `CRAM_MD5` & `DIGEST_MD5`. **Note that**
+  `PLAIN` or `LOGIN` send passwords in plain text over the wire to the SMTP
+  server; only use these methods in combination with TLS encryption.
