email validation
-
Hi! I have a file with a huge number of email addresses. I'd like to validate them to make sure that each email is well-formed, the DNS actually exists and perhaps SMTP validation. I found several web pages that can be used to validate single email addresses, but do you know any web page/tool to use with massive emails? Thanks Carlos
The Dundas Mailer[^] is free and has a
ValidateAddressmethod that will do the trick. cheers, Chris Maunder -

Apologies if this is totally unhelpful:
^[\w-\.]{1,}\@([\da-zA-Z-]{1,}\.){1,}[\da-zA-Z-]{2,3}$That is an email validation regular expression string. I have been using in a bulk emailer project and it works pretty well.Paul Watson

:confused::confused:
I was just marvelling at how little effort people have to go to nowadays to build huge lists of valid emails. (not you, them)

Mmmmm Regex's, mix that with a little perl, some Net::Ping and Net::SMTP, and you're all set, 30-50 lines later you're off to the races. *Drool* Sounds so fun, I almost feel like doin it even though I don't need it! :-D -Lunchy

just write something that reads mx records. (i wrote such a component last week during my study breaks. It's not super hard.) Then connect to the mailserver and try te send an email. it will reply if if the email exists or not. www.agilis.be

Something like this function (need platform SDK to compile):
BOOL ValidateEMailAddresses(CallContextObj *pCallContextObj) { pCallContextObj->LoadSQLStatementBuffer(7451); pCallContextObj->ParseSQL(); DBStatement *pStmt = pCallContextObj->ExecSQL(); if (pStmt) { DBConnection oUpdateConn; DBStatement oUpdateStmt(&oUpdateConn); int iVerifyCount = 0; if (pCallContextObj->GetApplication()->Connect2DB(&oUpdateConn)) { long lRecipientKey; char caDomainName[256]; char caDomainNameHold[256]; char caUserName[256]; int iResponse; strcpy(caDomainNameHold,cpUnknownStr); BOOL bConnected = FALSE; int iVerifyStatus; LPCSTR cpUpdateSQL = pCallContextObj->GetSQLStatementPtr(7453); char *cpWorkBuf = pCallContextObj->GetWorkBufferPtr(); char *cpUpdateBuf = pCallContextObj->GetCookieBufferPtr(); pCallContextObj->SetSQLStatement(""); CSMTPSocket oMailSock; while (pStmt->FetchNext()) { pStmt->GetCharBuf(1,cpUpdateBuf); lRecipientKey = pStmt->GetLong(2); char *p = strchr(cpUpdateBuf,'@'); if (p) { *p = 0; strcpy(caUserName,cpUpdateBuf); strcpy(caDomainName,p+1); } else { strcpy(caDomainName,cpUpdateBuf); strcpy(caUserName,cpUpdateBuf); } if (strcmp(caDomainNameHold,caDomainName)) { if (bConnected) { // QUIT strcpy(cpWorkBuf,"QUIT \r\n"); oMailSock.Send(cpWorkBuf,strlen(cpWorkBuf)); oMailSock.Receive(cpWorkBuf,pCallContextObj->GetWorkBufferSize()); oMailSock.Close(); bConnected = FALSE; } DNS_RECORD* ppQueryResultsSet = NULL; DNS_STATUS statusDNS = ::DnsQuery(caDomainName, DNS_TYPE_MX, DNS_QUERY_STANDARD, NULL, &ppQueryResultsSet, NULL ); if (statusDNS == ERROR_SUCCESS) { strcpy(cpWorkBuf,ppQueryResultsSet->Data.MX.pNameExchange); if (oMailSock.Create() && oMailSock.Connect(cpWorkBuf,25,"")) -

It worked fine to me.
