|How are bounces tracked in the Enterprise
Enterprise Edition has full support for bounced email tracking. There are
several ways in which an email message can bounce
- When the mail server receives a
positive response indicating that delivery is not possible. i.e. A user does
not exist on the mail server for the domain or no mail servers are listed
for the domain.
- When the recipients mail server is
currently down for one reason or another. Cases such as this may
not be a true bounce.
- Mail server accepts the message but
later rejects it for one reason or another.
Undeliverable Messages the
mail server will place these messages in the \failed\ folder. For example,
eNewsletter Pro Bounce Engine
scans this folder every 8 minutes (by default). Email addresses are
extracted from these failed messages and logged as a bounced address. The
failed message is then deleted to preserve space. You can change the
frequency with which bounced addresses are filtered by changing the eNewsletter
Pro Bounce Engine schedule under Scheduled Tasks in the Windows control panel.
If the receiving mail server initially
accepts the message then later rejects/returns it, the message is returned to
the bounced email address that was defined in the Administrative Setup.
This email address is the same for all users. This email account must be a
POP3 compliant address. The eNewsletter Pro Bounce Engine checks
this POP3 email account for returned messages after emptying the \failed\
folder. This task repeats every 8 minutes.
What happens to bounced
Each time the eNewsletter Pro Bounce
Engine finds a bounced address, it simply increases the Bounce counter in the
database for that specific email address. The email address is NOT
automatically removed from the database.
How do I remove Bounced Addresses?
To remove bounced addresses, use the
Filter Bounces tool in the user administration console. This tool allows
you to remove all addresses that have bounced X number of times. It is
recommended that you delete an address only after it has bounced several times.
If the recipient mail server is down when attempting to deliver the message, the
address is erroneously labeled as a bounce when in fact the address may be
