When testing this with by hand, you get the same result: $ telnet 62.149.128.72 25 Trying 62.149.128.72... Connected to mxd4.aruba.it. Escape character is '^]'. 220 mxcmd03.ad.aruba.it bizsmtp ESMTP server ready HELO me 250 mxcmd03.ad.aruba.it hello [212.79.224.10], pleased to meet you MAIL FROM: <t...@e-surland.com> 550 5.1.0 c9211j03M0E4mr00192RZ2 dominio non valido / invalid domain quit 221 2.0.0 mxcmd03.ad.aruba.it bizsmtp closing connection Connection closed by foreign host. The answer to the MAIL FROM command takes very long, which indicates (to me at least) that the receiving machine has an issue with resolving the domain (e-surland.com). This does not happen when you send a MAIL FROM: <some...@gmail.com>, so it seems dependant on your domain. The postmaster at aruba.it has to check why that is happening: I see no issues with the dns entries for e-surland.com. You cannot give answers about the remote system yourself. If your client is important to you, and the postmaster mail address is unreachable, make a phone call or use their website. This issue is completely unrelated to postfix now. -- Tom
