Likelihood of spam flagging

I have a domain (singularsys.com) with email and web site hosted by a
hosting company. I am having problems using their SMTP server for
sending email (long story), so I am considering using my ISP's SMTP
server instead.

This means that I would be sending emails with a sending address
...@singularsys.com
from a server in the domain
telus.net.

I know it works, but does it increase the likelihood of my messages
being flagged as spam? If so, is it significant?

I also have a link to the website (www.singularsys.com) in the email.
Could the combination of sending from an SMTP server other than that of
the sender domain plus an link in the email be too much? Or am I just
being paranoid?

Thanks,

Nathan

Using your ISP's SMTP server is usually a good thing and often you
will get better performance that way.

That is perfectly normal. If you look at the legitimate mail you
receive you will probably find loads of examples of this already.

It may cause some people to reject your mail as spam, but if it does
then those people have a problem of their own making. You will also
find some people reject mails if they contain HTML because they think
"only spammers use HTML" and because real men use plain text and don't
eat quiche. You will also find some people reject mails which have
Word or Excel attachments because "everyone knows that these contain
viruses". All these strategies may well block undesirable mail, but
they are block too much good mail as well so they don't tend to be
widespread in use. So one or two people may block your mails, but
they'll be having such a problem with blocking good mail that they'll
need to review their mail strategies, not you.

The bigger question is whether the telus.net SMTP server that you use
is on any blocklists. I suggest you put the IP number of the smtp
server you intend to use into this page:

http://www.dnsbl.info/quickcheck.asp

and see what level of blocking it gives. (Green across the board is
good). You might also try the address of your current SMTP server in
there as well, to see how they compare.

Some spam filters check the embedded links against blocklists to see
if it is a spamvertized site, but if your site has no history of
spamming then you shouldn't have any problem.
