We are having some major issues over the past week when forwarding mail to xtra. Mainly:

- delivery temporarily suspended: connect to mta.xtra.co.nz - connect to mta.xtra.co.nz[210.54.141.1]: 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 postmaster(a)xtra from elsewhere on 1 December, with no response so far. Typical log: Dec 7 14:19:26 skinner postfix/smtp[19226]: connect to mta.xtra.co.nz [210.54.141.1]: server dropped connection without sending the initial greeting (port 25) Typical telnet: $ telnet mta.xtra.co.nz 25 Trying 210.54.141.1... 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[19322]: 187FFA9EF2B: to=, relay=mta.xtra.co.nz[210.54.141.1], delay=27, status=bounced (host mta.xtra.co.nz[210.54.141.1] said: 550 Invalid recipient: (in reply to RCPT TO command)) 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.
