I'm working on a app which sends notifications emails. I know this is stereotypical for spam servers. I know the first question ist "How can I ensure what my server will not be listed as a spam server?" However I believe I should monitor my mailserver to ensure what every customer becomes his mails.
So the question: How can I check/monitor whether my server is listed as a spam server?
I really appreciate your help.
MXtoolbox (disclosure: I hold no relation to this site) has a great blacklist checking tool that checks all the major blacklists.
As for staying off them, make sure all your e-mails are opt-in and have an unsubscribe link within the e-mail body of every notification sent. Keep a record of all clients opting in, some hosting companies will charge you a small fortune if you get their IPs blacklisted.

Mailchimp, the online service for sending newsletters, has an statistics about how many people marked email you sent as spam. Does anybody know how this works? I am asking because I was thinking about how to implement this into my CMS which sends newsletters as well. Thanks for replies!
It's called FBL (feedback loop) and means that you register your MTAs (email sending servers) at the ISPs that supports FBLs (Yahoo, Hotmail etc.)
All you have to do is to sign up for every available FBL via their forms and then they will send you an email every time someone mark email sent from those servers as spam (spam complaints).
Then you'll have to parse those emails to get the information from it.
Have you checked Mailchimp Support?

An abnormally high bounce rate is another indicator. Look through your hard bounces, and read the SMTP replies. Spam filters sometimes leave little clues about why they blocked your campaign (See: http://kb.mailchimp.com/article/why-did-my-email-bounce-smtp-replies).

How do I make sure that emails from my website doesn't show up in Gmail's spam filter?
Are these emails from your website appearing in your inbox? or emails from your site appearing in other people's inboxes?
If its the first, add the the email addresses to your contacts list.
If its the second, ask people to add the email addresses to their contacts. Alternately, you can send messages that are good quality, not annoying, and not spam.
Also, read this thread How to stop Gmail from marking mails sent by my web app as spam?

Apologies if this is the wrong site - not really sure which site is best for this, but since it's SMTP-related (or is it?), I figured maybe this site had the best audience.
My company just set all of our live servers to route email through Critsend (at a cost). Apparently we've had some people complain about emails going missing, and this service lets us track it better...
I was pretty shocked, and said "There's nothing they can possibly tell us, that we can't get from the SMTP server logs!". However, I was given a huge list of features they support, including this:
Spam folder statistics with addresses
Apparently, they can tell us how many (and which!) emails went into spam folders.
I've done a little SMTP in my time, and I'm certain there is no way to get this information. So, what are they doing to claim this feature? (Note: Sadly, I don't have any access to actually see one of these reports).

I have set my MX record with Google
Mail, but google only provide 50 email
address for free is there any
possibility to create 50 email with
google and more with my own Web
hosting provider email server?
Unfortunately not. There's no way for MX records for a domain to distinguish between different addresses. However, if it's possible to create subdomain email addresses, you might be able to get away with creating a catch-all address in Google Apps and then setting filters to forward mail appropriately.
However, I think your best solution would really be to start paying for Google Apps if you're using it so extensively. Definitely worth it.

I am working on an email program and I want to add a basic way to detect spam based on the domain/sender of the mail. One service that I was looking at was gossip (http://gossip-project.sourceforge.net/) but I don't want to go to the hassle of setting up a dedicated Gossip server. I know that there are a lot of email blacklists (DNSBL's) and stuff out there that can give you an estimate of whether or not an email is spam based on the domain it was sent from. I'm wondering if anyone knows of one that I can just query from within a program by passing it the sender's domain and having it return the likelihood that the email is spam. I don't want a service that requires me to set up a server for it.
Anti-Spam Blacklists do list only IPs not domains. They can't list domains (of the sender) as the sender address can be (and usually is) forged.
So you can either lookup an IP in a DNSBL from where the mail was originating. Or you have to determine the probability of spam by analyzing the mail content. The latter is "expensive" in CPU cycles and other resources. In both cases you do not need a special server for that.
The better solution to prevent spam is at the server level. Block the mail before it enters your mail system. Then you don't have to mess with mail filters.
