Hello. The result is: ------------ 220 mailout1.t-email.cz ESMTP EHLO 251-43-13-46.tmcz.cz 250-mailout1.t-email.cz 250-PIPELINING 250-SIZE 15360000 250-VRFY 250-ETRN 250-AUTH LOGIN PLAIN 250-ENHANCEDSTATUSCODES 250-8BITMIME 250 DSN AUTH LOGIN 334 xxxxxxxxxx yyyyyyy 334 xxxxxxxxxxxx yyyyyyy 235 2.7.0 Authentication successful MAIL FROM:<jiri.pa...@email.cz> SIZE=519 AUTH=<> 250 2.1.0 Ok RCPT TO:<ji...@soukroma.cz> ORCPT=rfc822;ji...@soukroma.cz 555 5.5.4 Unsupported option: AUTH=<> ----- (why sends it ISPs smpt now ?! RSET ------- (send by my postfix == out) 250 2.0.0 Ok QUIT 221 2.0.0 Bye ------ Now is it <one command > <one replay>, but as you can see, id didn't help. Can this something to do with another packeting of stream against direct connection ? I thing, my Postfix should ignore the "555 5.5.4 Unsupported option: AUTH=<>" and continue. Or better do not send it at all - what is it at all? As you wrote: "If that is the case, then the server mis-implements SMTP command pipelining." Did you mean my server (my postfix) or ISPs server ? --kapetr P.S: the outputs are from wireshark (not edited from me) , so I thing "replies are received in this order". I have also checked by examining packets manually. -- Jak se vyhnout nachlazení a dalším zdravotním potížím v nepříjemném podzimním období?
