We are having some major issues over the past week when forwarding
- delivery temporarily suspended: connect to mta.xtra.co.nz
- connect to mta.xtra.co.nz[22.214.171.124]: server dropped connection
without sending the initial SMTP greeting
Has anyone seen any of these issues and knows anything about them?
We are also seeing issues since late November. I emailed
***@xtra from elsewhere on 1 December, with no response so far.
Dec 7 14:19:26 skinner postfix/smtp: connect to mta.xtra.co.nz
[126.96.36.199]: server dropped connection without sending the initial
greeting (port 25)
$ telnet mta.xtra.co.nz 25
Connected to mta.xtra.co.nz.
Escape character is '^]'.
Connection closed by foreign host.
The above is the most common behaviour, but apparently the connection
does stay open properly from time to time (I had to send a bunch in a
row to get this):
Dec 7 14:28:34 skinner postfix/smtp: 187FFA9EF2B:
delay=27, status=bounced (host mta.xtra.co.nz[188.8.131.52] said: 550
Invalid recipient: <***@xtra.co.nz> (in reply to RCPT TO
We also sometimes get "421 Service not available" before it drops the
connection, and sometimes we even get connection refused. But when
we're really lucky:
220 mta01.xtra.co.nz ESMTP server ready Thu, 7 Dec 2006 14:41:34 +1300
220 mta06.xtra.co.nz ESMTP server ready Thu, 7 Dec 2006 14:43:01 +1300
So, yeah, it looks like something might be up.
