邮件退信
公司自建服务器,有做spf记录,有做PTR,发送QQ、163、126、sina等不退信,在kloth.net查询,没有列入黑名单,发送gmail及部分企业邮箱退信,不知道什么原因,发送gmail退信如下:1)SMTP error, DOT: 550-5.7.1 [#### 12] Our system has detected that this message is
550-5.7.1 likely unsolicited mail. To reduce the amount of spam sent to Gmail,

请哪位指点下,服务器明明已经做了PTR及黑名单中,为什么还会退信,以及该如何解决,谢谢!!!
是google拒绝了你的邮件,直接找Gmail吧。 结果如何呢?
