is it fair/correct to check the existence of a mailbox for about 30/50 mail addresses/day?
As long as the domains support the VRFY command, there should not be any issue.
We must RSET and then QUIT every the smtp connection just after the RCPT TO answer because we must check the data but we cannot contact these users.
If you are using "RCPT TO" as a replacement of a disabled "VRFY", it means you are trying to verify emails on a server that has explicitly disabled the functionality.
Do you think that we may be blocked or reputation decreased if we activate this kind of recipient checking process?
Our servers will always reply 250 if we detect you are trying to verifies emails.
If a wrong address is inserted, our customer doesn't get paid for that contract.
The existence of an email does not mean it is not a wrong address. François _______________________________________________ mailop mailing list mailop@mailop.org https://list.mailop.org/listinfo/mailop
