krudmart.com is the main one.
krudmart.com uses EXIM and presumably has sender address verification
enabled. In response to sending mail, they check if your mail server
accepts an envelope from <> to your sender.
By default, Exim has a timeout of 30 seconds, and your mail server
seems to delay the SMTP greeting by about 30 seconds.
From what I'm reading about the greeting delay, it is a good thing,
right? I'm gathering that it is to protect against 'smtp slammers'?
I added a line to my /etc/tcp.smtp like this:
70.87.77.70:allow,RELAYCLIENT="",RBLSMTPD="",QMAILQUEUE="/var/qmail/bin/qmail-queue"
and ran:
tcprules /etc/tcp.smtp.cdb /etc/tcp.smtp.tmp < /etc/tcp.smtp
but the problem still seems to exist. When trying to send a message to
my friend at Krudmart.com, this is in my logs:
@4000000045bf74de0b893194 starting delivery 37: msg 8241251 to remote
xxx@krudmart.com
@4000000045bf74de0b894134 status: local 0/10 remote 1/20
@4000000045bf74fc27f7700c delivery 37: deferral:
70.87.77.70_does_not_like_recipient./Remote_host_said:_451_Could_not_complete_sender_verify_callout/Giving_up_on_70.87.77.70./
Is there a way to change the greeting delay for a specific host?
