Email Address Errors
If an addressing
error arises when sending email, you will usually get a bounce email returned
to you with an error message.
Possible solutions are described below.
- Spelling Error. The
most common error is a mistyped address, which usually produces a "no such user" error
message. Double-check the address, and if necessary phone the recipient and ask
them to send you an email so you can cut and paste their
address into your address book to guarantee
it is entered without error.
- Under / over-specification.
Occasionally you find an address is under or over-specified.
For example, you may receive an
email from a third-level domain
name like "mail.twenty.net", but their system is set up to only receive email addressed to
the second-level name "twenty.net", in which case you can
change the address and try again. Similarly, if the email is labeled "mail.twenty.net" and
you are sending to "twenty.net", then try sending to
the full third level domain name.
- Wrong Reply-To
Field. A not uncommon error is to configure
a different address in your "Reply-To" field from the "From" field, usually by
a spelling mistake. The Reply-To field is used by some email programs when the
address is different than the From address, for example when email is from
a list server and replies should go to the mailing list address.
However, for most people the Reply-To and From addresses should be the same, and if the
Reply-To field is different it can cause problems.
Check your bounced email to see if you sent it to the same address it was received
from. If you replied to their email with the Reply function, it might have been sent to the Reply-To field instead of the From field -- check if that address is different. If this is the cause, then reply to the email again, but manually copy
the correct address from the From field, and let the recipient know that they need to correct their Reply-To address.
Historical. The following suggestions apply mainly to older systems, and should
rarely be needed on modern system today, but are included for completeness
- Bang Addresses.
If the address uses the old "bang" format of specifying a path with exclamation
points, then the exclamation points might be mistakenly interpreted as shell script
commands and interfere with your message transmission, as in the following example:
slashes "\" in front of each exclamation point will sometimes tell the destination
computer that they are just separators and not instructions.
- Bitnet. To send email to a user on Bitnet, you sometimes get an address
that doesn't have a domain name specified, and you have to append the name ".bitnet".
that doesn't work, change the at sign to a percent sign, and send it to a Bitnet
- Compuserve. Old Compuserve addresses are made up of two numbers separated
by a comma and no spaces, followed by "@compuserve.com"
comma causes problems. You can try changing it to a period.
- FidoNet. Fidonet addresses are made of a user name and a system node
number. System node numbers are made up of a zone, network, and FidoNode number
for the U.S. and Canada, 2 for Europe and Israel, 3 for Pacific Asia, and 4 for
network number in that zone
The BBS number on the
can construct an Internet address from a FidoNet address by prefixing the zone
with a "z", the network with an "n", the FidoNode with an "f", reversing their
order, appending ".fidonet.org", and prefixing with "firstname.lastname@".
send to an Internet address a FidoNet user sends an email to UUCP, enters the
node number of a UUCP gateway in the node-number field, and puts the Internet
address as the first line of the message.
