Hello

I am using a test server from a dynamic IP. I am testing a CMS website
and I have an "admin" and a "user" both with different "real" email
addresses.

I have lots of email addresses I can use for this purpose, but because
the MX records don't point to my server, I am getting rejections.

The only email I can send to (which I can access) is the email my ISP
gave me:

Feb 28 20:25:37 localhost postfix/smtp[12203]: EFD622CF8F7:
to=<honeyant@ozemail.com.au>, relay=filter.iinet.net.au[203.0.178.192],
delay=2, status=sent (250 ok: Message 167078551 accepted)

None of my web hosting account emails work. This is unfortunate of
course, because I can created unlimited addresses. Example log below:

Feb 28 19:48:01 localhost postfix/smtp[12071]: 47CDC2CF8F7:
to=<a@hobbs.id.au>, relay=mail.hobbs.id.au[205.234.148.160], delay=3,
status=bounced (host mail.hobbs.id.au[205.234.148.160] said:
550-Verification failed for <apache@localhost.localdomain>
550-unrouteable mail domain "localhost.localdomain" 550 Sender verify
failed (in reply to RCPT TO command))

My final option is the email address I got with my mobile phone
provider. This seems to work (as per the log), but it must be getting
blocked in a similar way to the above (??):

Feb 28 20:25:36 localhost postfix/smtp[12201]: BF56B2CF8F6:
to=<urbits@three.com.au>, relay=smtpin2.three.com.au[202.124.68.52],
delay=1, status=sent (250 ok 1141119399 qp 16981)

So, unless I'm way off track, this must be a typical requirement. Does
anyone have a suggestion about how I might configure either my email,
or my MX records to make these other servers accept my test emails?

Cheers
Simon
