i am writing a sendmail module to email some things to my site users. for testing it i use my own email at yahoo to receive this email. but something woeful happened. about 1200 sent to my email address at yahoo at a moment and yahoo sent all of them to spam box. now i can't send any email to yahoo addresses and my server gives me this message in mailq:
delivery temporarily suspended: host g.mx.mail.yahoo.com[98.137.54.238] refused to talk to me...
how can i solve this problem?? many users of my site have yahoo email address.
my server uses postfix. thanks for helping .
