this is getting much weirder. following the message below, i tested both
my backup and primary to see if they implemented help for qmail.
here's what happened:
when i test help by doing the following:
from an ip inside the local network:
>telnet mailhost.otec.com smtp
[dkelley@mx1 qmail]# telnet mailhost.otec.com smtp
Trying 209.3.117.5...
Connected to mx1.ny.otec.com.
Escape character is '^]'.
220 mx1.ny.otec.com ESMTP
help
214 qmail home page: http://pobox.com/~djb/qmail.html
from a remote ip:
% telnet mailhost.otec.com smtp
Trying 209.3.117.5...
Connected to mx1.ny.otec.com.
Escape character is '^]'.
220 *********************
help
502 unimplemented (#5.5.1)
i tested the backup (which is located on a different block in a different
geographic location) the exact same way:
from an ip inside the local newtork:
% telnet dev1.gc.ny.otec.com smtp
Trying 10.0.50.102...
Connected to dev1.gc.ny.otec.com.
Escape character is '^]'.
220 dev1.gc.ny.otec.com ESMTP
help
214 qmail home page: http://pobox.com/~djb/qmail.html
from a remote ip:
[dkelley@mx1 qmail]# telnet dev1.gc.ny.otec.com smtp
Trying 64.209.222.102...
Connected to dev1.gc.ny.otec.com.
Escape character is '^]'.
220 *************************
help
502 unimplemented (#5.5.1)
this appears to be hopelessy weird. both smtp connections are made through
a firewall, which leaves port 25 open for the respective machines.
mailhost.otec.com, after a very recent upgrade, runs qmail-1.03 with the
qmail-remote ptach for qmtp delivery, and the qmail-queue patch for use
with qmail-scanner. i've looked at the code (both pre and post patch), and
can't figure out why this would occur.
i've tried this from both a windows terminal and a linux xterm.
anyone have any idea how this could happen?
thanks-
dan
