Thanks Ole
Well, I could telnet from a different host, so I just rerouted the connection up
my vpn and made it appear to be from my other box. I'm waiting for a call back
from the ISP, time to get the BS filter ready. Thank for putting my mind at
rest.
>From my end I was receiving this bounce:
Mar 9 18:53:47 scanmail sendmail[19712]: j29H806h013343: to=<[EMAIL PROTECTED]
cable.com>, delay=07:45:47, xdelay=00:00:01, mailer=esmtp, pri=40802345, relay=s
hawmail.shawcable.com. [64.59.128.220], dsn=4.2.1, stat=Deferred: 452 4.2.1 mail
box temporarily disabled: [EMAIL PROTECTED]
So my machine kept tring to deliver the mail, as that was a tempfail for the
mailbox.
Then at some point it, it appears that I was blacklisted because the bounce
switched to:
Mar 8 16:38:38 scanmail sendmail[3371]: j28GoNOs030800: to=<[EMAIL PROTECTED]
able.com>, delay=05:48:14, xdelay=00:00:00, mailer=esmtp, pri=31441946, relay=sh
awmail.shawcable.com. [64.59.128.220], dsn=4.0.0, stat=Deferred: Connection rese
t by shawmail.shawcable.com.
Which stopped delivery to all domains hosted on that machine. It appears that
the tempfailing
mailbox triggered some thing on that machine that blacklisted me. (think it was
while I was on
the phone with the ISP...)
What blows my mind is that I was not the one tempfailling the delivery, that
should not count towards
what ever they are using to count failed connection attempts, my machine is
doing the right thing by
tring to deliver this piece of mail (maybe too often), that was deferred by
them. If their machine would
perm fail the mail, my box would stop trying.
I'm just making sure that I have everything right, on my end
My question is what would be considered acceptable for a retry interval?
1 min, 5 min, 1 hour?
Jerry
