Hi, Here is my problem. I try to send one message which is refused by remote mailer (at MAIL FROM Level) with error:
552 Requested mail action aborted: exceeded storage allocation wireshark tcp stream: 220 81.52.180.21 ESMTP EHLO relay.com 250 81.52.180.21[relay.com] Please to meet you 250-PIPELINING MAIL FROM:<+33612345678/TYPE=p...@origin.com> 552 Requested mail action aborted: exceeded storage allocation RSET 250 Ok QUIT 221 Service closing transmission channel When Postfix sends the mailer-daemon, there is in the notification: host [81.52.180.21] said: 250-PIPELINING 552 Requested mail action aborted: exceeded storage where 250-PIPELINING concerns EHLO command. Why for an error on MAIL FROM, postfix adds EHLO reply? BR
