I work on a project witch sends registration e-mails and other notifications. I can’t find anywhere what is the limit for one server sending e-mail to yahoo per hour or day, because 80% of our users have yahoo mailboxes and many just don’t receive their emails with confirmation links.
Yahoo accounts can receive any number of E-mails. But Yahoo has limits of how many mails can be sent. It is 100 a day. Only 100 addresses per mail, with not more than 50 of them to the same domain.
In Yahoo help link:http://help.yahoo.com/l/us/yahoo/mail/classic/vsp.html;_ylt=AjJpahfYyq1MKodxgJJxpzQduyR4;_ylc=X1MDMjE0MjQ3ODk0OARfcgMyBGZyMgNzYnRuBG5fZ3BzAzAEcXVlcnkDZW1haWwlMjBsaW1pdHM-?query=email+limits&Ask=Search+Help&lang=us&prop=mail&lsp=classic&sp=classic&.p=yahoo
It says "How many emails can I send via SMTP? Is there a limit?
yes, your outbound email messages are limited to 500 per day, and each message can be sent to no more than 100 contacts…"
Hope that helps!
Good Luck!
