Conferencing Module.
Configuration for sSMTP
(1) mailhub
This is the computer responsible for handling your outgoing mail. It could be the
SMTP server of your ISP, or a departmental mailhub. Use the fully-qualified domain
name (foo.bar.baz) of the mailhub; if it uses an unusual SMTP port number, use the
colon syntax
foo.bar.baz:2525
Otherwise sSMTP will use the standard SMTP port number (25).
(Note that sSMTP can support a user-dependent mailhub with the 'reverse aliases'
feature, for which see the man page.)
Please enter your mailhub []: mail.yourcompany.com
Enter the fully qualified domain name of the computer handling outgoing
mail.
(2) FromLineOverride
This specifies how sSMTP handles the From: line of outgoing mail. If
FromLineOverride=YES, sSMTP will leave the From: line alone if it already exists.
If FromLineOverride has any other value, or there is no From: line, sSMTP creates
the From: line using your username (or the -f command-line option), and the value of
the rewriteDomain option (step (4), below). If you use a mail user agent (MUA; e.g.
mutt, pine) I recommend using YES and having the MUA set the From: line.
(Exception: the 'reverse aliases' feature can be used to set up a particular From:
address for each user, in which case don't use FromLineOverride=YES. See the man
page.)
FromLineOverride? [YES]:
Specify how sSMTP handles the From: line of outgoing mail.
(3) hostname
sSMTP uses the hostname of your computer to identify itself to the mailhub, and in
the Received: headers of the outgoing mail. This has relatively little effect on how
the mail is handled. Use the fully-qualified domain name (FQDN) of your
computer(foo.bar.baz). If it doesn't have a FQDN, use some name for your box.
Hostname of your box [conf01.yourcompany.com]:
Enter the host name of your computer handling outgoing mail.
(4) rewriteDomain
Please enter the mail name of your system.
sSMTP uses this value to add a domain to unqualified e-mail addresses(addresses
without an @-sign).
