javamail - Maximum number of recipient in Java Mail -

-

i working on project involves sending emails using java. using javamailx module( had imported). i know maximum number of recipients whom can send our email ( mime message consisting of message, subject , attachments ) in 1 go. limit on number of recipients can emailed together. have searched online , on stackoverflow , there no clear answers. using gmail smtp server send emails gmail accounts , yahoo smtp server send mails yahoo accounts. do maximum number of recipients depend upon these smtp servers ? if default limits on them ? personal experience can tell academic email allows sending mails multiple people in 1 go ( whole mailing lists consisting of 200-300 people). not sure how works in end, if go in small groups of recipients or in total.

no limits specified in api documentation, limits inherent in implementation (i.e. memory).

also, sending and/or receiving smtp server limits reached before limits imposed implementation.
