You sent mail to a mailing list ([EMAIL PROTECTED]). For some reason
this mail message is being relayed by mail.speakeasy.net (a mail server).
Most ISPs have anti-relaying provisions in place. The normal method is to
block SMTP port 25 (Earthlink does this).
Another method that is used by many ISPs (especially those using POP3 mail
daemons; Hotmail included) is to have the user get mail from the server
first. The reason for this is that the mail server must record your hostname
and IP address, which are placed on a list of those allowed to send outgoing
messages through the mail server. This window remains open to you for some
time period (usually 30 minutes) from the time you check for new mail.
Therefore, you can check for new e-mail and wait up to 30 minutes before
sending any mail out through the mail servers. After 30 minutes, you will
need to re-check for new e-mail.
Check IP addresses:
no2:/opt2/home3/expita>nslookup repairworld.com
Server: localhost
Address: 127.0.0.1
Name: repairworld.com
Address: 216.254.1.71
no2:/opt2/home3/expita>nslookup mail.speakeasy.net
Server: localhost
Address: 127.0.0.1
Name: mail.speakeasy.net
Addresses: 216.254.0.193, 216.254.0.194
Notice that both are in 216.254.xxx.xxx which makes me think they are
related. A search of ARIN for the block IP addresses (called Netblock)
controlled by a domain (ISP) shows:
no2:/opt2/home3/expita>arin 216.254.1.71
Speakeasy Network (NETBLK-SPEAKEASY-2) SPEAKEASY-2
216.254.0.0 - 216.254.127.255
Plum Consulting, Inc. (NETBLK-SPEK-PLUMCON1-0) SPEK-PLUMCON1-0
216.254.1.64 -
216.254.1.95
Sooooo, the two domains are related. A check for the MX (mail exchanger)
records at repairworld.com shows:
no2:/opt2/home3/expita>nslookup -q=mx repairworld.com
Server: localhost
Address: 127.0.0.1
repairworld.com preference = 10, mail exchanger = mail.electronix.com
repairworld.com preference = 20, mail exchanger = mail.speakeasy.net
So, repairworld.com uses the mail.speakeasy.net mailer daemon. Hence, it's
incorrectly configured because it is actually blocking mail from the same
domain. Contact the owners to have them check their configuration files.
Owners can be found by using whois:
no2:/opt2/home3/expita>whois repairworld.com | more
