How do I combine my to yahoo emails into one?

Do yahoo/hotmail limit number of emails/second they recieve from one address?

• I have a list of legitimate 100,000+ subscribed emails to a website i manage. Majority of emails are yahoo or hotmail. The current mechanism (using sendmail on linux scripted in PERL) i use is to send the email to myself and Bcc 100 recipients (which fires 1000 sendmail processes) . I'm redesigning the send mechanism so as to send the email with one recipient (which would mean 100,000+ sendmail processes). Question: do yahoo/hotmail/other s limit the number of emails they receive per time unit (sec/hour/day/etc) from one address (e.g [email protected]) Other related questions (the server is a 3GH cpu, 1GB mem, and CPU load hovers around 0.10 most of time) 1- how fast should i fire those sendmail processes (e.g, 10/sec etc) 2- what are the ideal flags/option to use with sendmail - i currently use -t 3- if there is a limit, do yahoo/hotmail defer delivery or dev/null the email? thanks.

• Answer:

  there are tricks to employ! You can batch the e-mails for each host and throttles the mails to see what you can get away with. By providing 100% correct and reasonable headers you can virtually eliminate the /dev/nulling of your mails. No reputable mail service would do a wholesale delete of your mails, unless you are black listed. If they do you can apply for white list status. I've done lots of perl mailing, avoiding sendmail and using net::smtp directly. I get reasonable results using net::smtp whereas sendmail just takes what you give it and tries to send it off. Sorry I don't know of any hard limits that any providers have. I've just always tried to be a good netizen.
