答：您好，檢查日志您是使用的postmaster賬號(hào)發(fā)送的，默認(rèn)postmaster是超管賬號(hào)不對(duì)外發(fā)送郵件，建議您使用其它郵箱發(fā)送試試,我司找了其它郵箱測(cè)試可以正常發(fā)送，非常感謝您長(zhǎng)期對(duì)我司的支持！

問：emily@benlyalloy.com 這個(gè)賬號(hào)也發(fā)不出去 這應(yīng)該不是超管賬號(hào)吧
答：您好，從您截圖看， ，這是對(duì)方郵局的設(shè)置問題，請(qǐng)web方式發(fā)送測(cè)試是否正常，可以嘗試讓對(duì)方將您郵局設(shè)置加白名單中再觀察是否收發(fā)正常，謝謝
咱們郵局現(xiàn)在運(yùn)行是沒問題的，個(gè)別郵箱收發(fā)設(shè)置不同郵局供應(yīng)商和郵局系統(tǒng)，因此任何郵局都不能保證百分百全部郵局郵件都收發(fā)不出現(xiàn)異常，因此需要根據(jù)退信進(jìn)一步核實(shí)具體原因并優(yōu)化
