The argument of userx@[1.2.3.4] is rejected as an "illegal" address (although this is in fact the RFC correct way to do it). Interestingly, I can use userx@1.2.3.4 (note lack of brackets) successfully, but since this is technically not RFC compliant, many MTAs will refuse to accept it (e.g., postfix, and probably others). For example: 220 mx1.mfn.org ESMTP Postfix ehlo mfn.org 250-mx1.mfn.org 250-PIPELINING 250-SIZE 10240000 250-VRFY 250-ETRN 250 8BITMIME mail from: userx@mfn.org 250 Ok rcpt to: antisocial@192.168.155.108 501 Bad address syntax rcpt to: antisocial@[192.168.155.108] 250 Ok quit 221 Bye ---------------------------------------------------------------------- You can respond by visiting: https://sourceforge.net/tracker/?func=detail&atid=100103&aid=967454&group_id=103
