Does anyone know if the mail plugin has a limit on the number of addresses that can be used in the “to”, “cc” of “bcc” address? I am trying to send an email that has one to address and 800+ bcc addresses. I know that all the addresses work individually, but when i try to do the mass mailing I get the error “Illegal character in domain”. The 800+ addresses are compiled as dataset the converted to text using a comma as the separator.
I don’t know if the limit is in the plugin or in the protocol (i.e. the Mailserver).
Why don’t you break it up in batches of 200 addresses and try that.
putting a bunch of emails in the BCC is a bad idea. If they are internal corporate emails, you should be using a list server. If they are external emails and you are sending as part of a newsletter or something, you should send them separately. If you don’t want to send them individually through your own email server, use a third-party service like MailChimp, CampaignMonitor, or MadMimi. They all have simple API’s.
