Hi,

As i am trying to use jscape email validation program, i have a doubt ,


I want to verify 1000 email ids one by one from this code but if i do that to check email is valid or not, it will check that by pinging to the domain server,
then checks mx record again pinging to the domain, since we are hitting others domains many times, any chances that our ip will black list ?

verifying email continously whether black list our ip ?

Hi,

The email verification code does not perform a ping, but rather a DNS lookup. This should not result in any sort of "blacklisting", however if this were a concern then you could simply store those domains in a file or in memory that you know to be valid so you don't need to do a lookup.

hi,

thanks for your reply.

plz correct me if i am wrong.

actualy in email verification if we do syntax checking ,dns look up then smtp check , if we check dns lookup for checking the domain is valid or not but not for email, if i want to check email through smtp check i need to check in perticular mail server to check its valid or not.so for 1000 emails to verify if i am hitting mail server many times ,then any chances of black listing ?

i am new to this , if u explain in detail or give me the exact link related with it ,it will b very useful for me.

"then any chances of black listing"

This really depends on the SMTP server. It's possible. It really depends on how many email addresses you are talking about. If you are talking maybe a few dozen, then not very likely, but if you are talking 1000's then yes it is possible.
