the issue is sending mail
Yes, that's possible with Webmail. One of my mail providers
uses "squirrelmail", it's quite nice after I found all places
to disable JavaScript.
You can use the MSA of your provider.
Which provider?
Your mail provider, the one you send and receive mails with.
If you have more than one it's fine, at one time I had six,
now only three (a minimum to bypass DNSBL problems is two).
Who says that that provider has an MSA
Just ask them, or check their mail FAQ for "roaming". We're
talking about SMTP, and while some details are hairy it's in
essence still S = Simple.
or that it is accessible (port 25 blocking)?
Blocking port 25 is utter dubious, find a better ISP with an
abuse desk, not spamcast. For an MSA you'd use port 587. See
chapter 4 in draft-hutzler-spamops-04:
| Best practices are:
| o MSAs MUST support the SUBMISSION port, for MUAs accessing
| from outside the MSA's local environment.
don't publish a "sender policy".
Associated with which domain
All your domains, don't publish a "sender policy" if you don't
know what it means. Now that's obvious, isn't it ? Bye, Frank
