The issue of Spam and Mail Servers and legitimate use

[dejavue82]

Hello,

I am currently hosting an asp.net site on a shared crystaltech server,
which involves sending email via their mail servers. The problem is
that most of crystal tech's mail servers have been marked as 'spam
servers', and therefore email sent to aol or yahoo accounts are
rejected. This is of course not acceptable for a commercial online app
that depends on email messages getting received by its users.

Is this the case with most mail servers online? Is there a way around
this? What is a web app developer to do, whose intentions is not to
spam, but whose app requires the legitimate use of mail servers?

Thank you for your time and help.

Regards,

Jim

Either use your own smtp server or host at an ISP which is not blacklisted.

Hi Juan,

How does one go about finding this out about a given ISP? Is there a
list?

Thanks.

You can query any of several public services.

If your hosting company is on a blacklist for mail spamming then you should
"only" think about finding a reputable hosting company and dumping them
ASAP. You get blacklisted for allowing hosters to send out spam and doing
nothing about it - this type of company are usually very unreliable and you
should expect problems with support down the line as they are usually only
interested in getting money in and dont normally give two hoots when
problems arise.

Hi John,

That makes sense, however, except for this spamming issue,
CrystalTech has been a pretty good host and answers questions very
promptly. That's why I was a bit surprised when this problem came up.

btw, the address of my current mail server is

maila62.webcontrolcenter.com

On the other hand, I'm not sure how an ISP could prevent a user from
using their mail servers to spam. And when a company like yahoo or aol
blacklists them, it's already too late.

Maybe you should look for another reason why your mails are bouncing as spam.

That mail server has the IP 216.119.106.40
and neither Spamhaus nor Spamcop list it..

well even the ISP I use has been blacklisted before, but credible companies
manage to get themselves removed within a couple of hours and respond to the
issue that caused them to be blacklisted. Spamhause etc. have procedures in
place to get your company removed. If your ISP are good (and I personally
cant comment on them) then you should ask them what the problem is and how
they intend to deal with it.

It may be as Juan suggested that there is a different reason why your mails
are being rejected.
