ESMTP error malformed address: ORCPT=rfc822

  • 772

when trying to send a mail out I am seeing the folowing error in the maillog

client address has been obfuscated

Apr 5 18:15:18 my.mailserver.co.uk postfix-01/smtp[10626]: 1234567: to=<[email protected]>, relay=mail3.gridhost.co.uk[95.142.156.18]:25, delay=1.4, delays=0.15/0/1/0.24, dsn=5.0.0, status=bounced (host mail3.gridhost.co.uk[95.142.156.18] said: 501 <[email protected]> ORCPT=rfc822;[email protected]: malformed address: ORCPT=rfc822;client@clie may not follow <[email protected]> (in reply to RCPT TO command))

I performed the following manunal test and was able to reproduce the error

$ telnet mail3.gridhost.co.uk 25
Trying 95.142.156.28...

Without the DSN response request it works ok

RCPT TO: [email protected]

if I try without the using postfix-2.6.6-2.el6.x86_64 on centos 6.8 any help appreciated, thanks
