once users have added their e-mail addresses to the 3Com IP 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).
