Options for Sending e-mail
These options affect the behavior of all e-mailer signal blocks.
SMTP Server URL Field
Supply an SMTP server domain name. Typically, this is the organization’s domain
name with the sub-domain smtp prefixed, as in smtp.organization.com, but quite
often it could be something else. It may or may not be the same as the POP3 server
URL. If in doubt, check how the e-mail client is set up at any PC on site or check
with the organization’s MIS department or Internet Service Provider.
NOTES:
1 This field must be completed before the server protocol can be started.
2 Avoid “raw” IP addresses; they can change. Use fully qualified domain names instead.
3 Avoid fictitious IP addresses or domain names; they cause excessively long DNS lookups with
each attempted mailing. This is a real problem when not using SMTP Express, because the
server cannot process any other signals while waiting for the SMTP server to “come back.”
(This is only a problem for the SMTP server name; it is not a problem for fictitious domain
names in the addresses of outgoing e-mail.)
cc: Field and Checkbox
This field accepts a comma-separated list of e-mail addresses (without real names).
The purpose of this field is to assist system managers who are monitoring outgoing
e-mail. If a high volume of mail is expected, we recommend setting up a separate
e-mail account name for this purpose.
A check in the checkbox indicates that this information is sent with every e-mail.
Lookup Substitution Defaults Checkbox
For more information about text
substitution, see “Text
Substitution Directives” on page
48.
Text substitution directives are normally replaced with the contents of text
substitution registers. The contents of the registers are defined at run-time. If a
directive invokes an undefined register, it is replaced with a null string (essentially
removing the directive — and substituting it with nothing).
Checking Substitution defaults, however, directs the server to use the directive’s
parameter number to lookup a record with matching ID field in the eMail_Subst
table and to use substitution text found therein. If the register in question has a
defined value, that value is used, as usual; only when a register is undefined does
this default action take place.
For example, if register 3 is undefined and Substitution defaults is unchecked, then a
directive that invokes this register (e.g., “Room C{3}” in a message's subject header
or body text), is removed (replaced by nothing), yielding the result “Room C.” If on
the other hand, Substitution defaults is checked, the directive is replaced by the value
of the substitution field in the record in the eMail_Subst table whose ID field
contains the value 3. If that record exists and its substitution field contains “525”
then the resulting string would read “Room C525” — and this is what would be sent
in the e-mail.
Queue Messages Checkbox
SMTP Express is a third-party
product which can be obtained
from the following web page:
http://www.quiksoft.com/ea
symail/smtpexpress/
Since the server cannot respond to incoming signals while waiting for an e-mail
message to finish sending, it is preferred to send messages in the background. A
check in this checkbox permits such an option by queuing messages to the SMTP
Express application which does the actual sending.
