It is important to remember that many individuals and many small
companies use personal or "vanity" domain names.
These domain names appear in their "From:" and "Reply-to:" addresses on
their outgoing e-mail messages, but SHOULD NOT be presumed to indicate
where the e-mail in question is arriving from.
For example, I might be travelling somewhere and sending e-mail messages
from an inhabitual location: a cruise ship Internet cafe, an Internet
access kiosk above a post office location in Beijing, a coffee bar, or
other such public-access location. In such a situation, I will typically
have NO control over what outgoing mail server is sending my e-mail
message, and since my being there is temporary I obviously don't want to
put a return address on my mail that would be connected with the location
where I physically am at the time.
You need to use your email service provider's Message Submission Service.
That should be available to authenticating clients on port 587.
Alternatively, use their webmail. If your Internet cafe is willing to relay
your email, then they're willing to relay spam, too, and should therefore
be blacklisted.
