Server Will Not Send Mach5 Mailer E-mail to External Addresses
Server 5.0 And Later
you are using Exchange Server to send your e-mail merges, you may
experience difficulty sending e-mail to external addresses. If so,
do the following: In the Exchange Server Configuration Manager,
go to the Internet Mail Service configuration, Routing tab and turn
on "Reroute SMTP mail", then press the Add button and
add your domain name (in the form 'yourdomain.com'). Select "Should
be accepted as inbound" and press Ok until all windows are
Server 4.0 And Earlier
Unfortunately, there is no such fix for Exchange Server
4.0 and earlier. You should contact your Internet Service Provider
and use their SMTP server rather than relying on your internal Exchange
If you are having
problems sending e-mail, it is most likely because of your ISP,
not because of Mach5 Mailer.
To prevent spam,
most ISPs do not allow you to use their SMTP server if:
- You are not
connected via one of their phone lines (i.e. if you are not using
one of their ISP addresses)
important: you must send e-mail as a user of that ISP.
For example, if the Mach5 Software marketing team wants to send
an e-mail to all of our clients, we must use an e-mail address
@mach5.com. If we were to send an e-mail with the From:
field set to a non mach5.com address, our SMTP server would reject
every e-mail message.
The moral of
the story is to use an From: address @yourisp.com
or @yourdomain.com. If you are still having problems
and are connected to the Internet through an ISP other than the
one used for the SMTP server, you should connect to the ISP you
are using for your SMTP server.

If you are having trouble
sending e-mail with Mach5 Mailer, you should follow the
procedures in this document -- they will help us solve the
problem. You should only follow the instructions in this
document if you are having e-mail problems, and
are receiving errors like "E-mail messages could not be sent
to one or more of the following addresses...". The information
on this page is not applicable if you are having
the large majority of e-mail sending problems can be resolved by
reading this document.
- First, launch
Mach5 Mailer, and click cancel until you are in the main Mach5
Mailer window. Click Help and then About.
- If you have
a version before 1.35, you must download a version
after 1.35 (the latest version can be obtained here). If you have a version of Mach5
Mailer after 1.35, you do not have to download the latest version,
but it is a good idea -- we may have fixed your problem in the
latest version of Mach5 Mailer.
- The reason
why we want you to have Mach5 Mailer 1.35 or later
is that we have created a special debugging file that allows us
to figure out exactly what is going wrong.
- This debug
file is called 'smtp-log.txt', and is created
and initialized each time you launch Mach5 Mailer. It is stored
in the main Mach5 Mailer directory, which should be 'C:\Program
unless you changed the directory when you installed the software.
- Run Mach5
Mailer and send e-mail to a few addresses. If you are consistently
having problems with certain addresses, please include those in
the debug e-mail send. Close Mach5 Mailer.
- Attach the
'smtp-log.txt' file to an e-mail message to firstname.lastname@example.org.
We'll figure it out and get back to you.
