Re: [twsocket] ...SMTPClient
Hello Arno. Thanks for mentioning RcptNameAdd(...). It's parameters are strings. I need to add up to 200,000 names to the ToList, which could be about 4,000,000 characters. As each email address is added to the list, the memory handling might make this become very slow. Can T...SMTPCli handle this quantity? What are the alternative ways? (You mentioned this was the easiest way.) It would be best for me if I could just set one name for the Bcc. Thanks.

Now I am incorporating the code into another project, and I would rather use Bcc instead of cc - because I don't want the receiver to know who else the message is being sent to. Is Blind carbon copy possible with this component? Of course it is. The easiest way is to use method RcptNameAdd(const ToList, CcList, BccList: string) as shown in MailSnd demo in order to specify the recipients. List separator is either ";" or ",". A Bcc recipient simply isn't listed in the email header. Means do neither assign Bcc recipients to property HdrTo nor to HdrCc. -- To unsubscribe or change your settings for TWSocket mailing list please goto http://lists.elists.org/cgi-bin/mailman/listinfo/twsocket Visit our website at http://www.overbyte.be

Most ISPs have blocks on their SMTP relay servers to prevent mass mailing by spammers, typically a few hundred or thousand messages a day, after which your account may be blocked. There may also be a limit of 25 to 100 recipients per message. So unless you are sending using your own SMTP relay server, sending 200,000 emails is unlikely to be an issue, you won't be sending any atall. I'm sure there is a limit in the SMTP specs for recipients, but you are more likely to hit an ISP limit first. Also, you may find emails send using BCC are more likely to be detected as spam, it's much better to individually address emails, although still within your ISP limits. This is how my own mass mailer works, written with ICS 15 years ago and hardly touched since.
