*Message size is over 1GB.
*The server will 'greylist' hosts. It will always defer (cause a temporary delivery failure) messages/connections under the following circumstances:
*Sending host in a DNS
*Header syntax errors
*Recipient rejected by the primary MX (It does a call back to the primary MX if it is available)

To force
etrn #your-domain.co.uk
quit
221 relentless.aa.net.uk closing connection
Note that tertiary-mx has various measures in place to discourage spam. You need to wait until after the "220 You are 2001:8b0:0::1" line is printed before you can issue the etrn, which may take a few seconds. Mismatching forward/reverse DNS etc. may upset it when you try to telnet in. If possible telnet in from your mail server itself, as that is more likely to look trustworthy.
