Last week we could send meails fine, this week we cant... (with our exchange server using our own domain name)

I just gave xnet a call to see if anything had changed on there end and they said that nothing had changed, but they had always blocked port 25 on everything except for themselves and a few others, just wondering if this for some reason wasnt having an effect and now is, or if it is something on our end.

Hello AllNightNerding,

The only way this would have been working in the past with us was if your connection had an assigned static IP. If it suddenly stopped working i would think the static was removed. If you would like to PM me your username or account number i can have a look into it for you.

Hi there,

I just tryed trial and error :D and rather than sending it through the pop connector or something like that, I changed it to send through smtp.xnet.co.nz and now the emails are working :D

Is this ok for xnet?

Yes, this is the correct setting which all Xnet customers should be using unless they have some special requirement.  Using Xnet's SMTP server will avoid any issues with Port 25 Blocking.

The correct e-mail settings for Xnet customers are on this page:

I can assure you that about 3 weeks ago port 25 was reachable since i sent some emails from mums place on my laptop without having to start a ssh tunnel and get it thru that way.

Using smtp.xnet.co.nz isnt viable if you want your emails to reach the recipients inbox vs spam folder, and I dont know why xnet dont just put the IPs in the policy list and ignore complaints about spam from them since the policy lists should make them not acceptable sources for direct to mx delivery.

If your clients have a proper spam filter then what server it comes from should not matter. Also If you are using xnet as your isp an easy workaround is to setup a catch all with xnet at a low priority mx record. This shows xnet as a reliable source for your domain name. ie mx priority 5 --> adsl connection, mx priority 10 --> smtp.xnet.co.nz. Then set up a pop concentrator on exchange to check the catch all. This is also useful for when you need to take your server down for maintainance.

Sending email direct from your host is not a good idea as your ip address will be classed as a dynamic host or in a "non server" pool. This makes it very easy to get on blacklists and very hard to get off them. It is alot easier to get an isp mail server off a blacklist than a host as it affects so many more customers.




Hmmmm

Yes, thats why you dont send it direct from the ip but relay thru your own server that has smtp auth on it.

Virtually nowhere accepts mail direct from a dynamic IP address that is on a policy list. By listing your dynamics it means you dont have to worry about them generating spam direct to the recipient mail servers since they will never take it. It seems the spamware is smart enough to take the smtp settings from mail clients and to try things like mail.ispname.whatever and smtp.ispname.whatever for relaying via.

I would never include an isps email server in my MX or more importatnly SPF records because anyone could then impersonate me via that server. I have just pulled the spf records at the moment since they seemed to be no help with getting emails thru to xtra and it means I can use other smtps when needed, but it is hardly a solution.

I use Death2Spam MX records. They proxy to my dynamically assigned static ip through orcon.
SSL SMTP from my desktop to my server. then out via orcon’s SMTP server.

I never have a problem with my email being classed as spam.





Hmmmm

The way that I have it configured is every account is done through the small buisness pop3 connector for every individual user.

so that way I hin it should hopefuly not end up in spam folders, as I know when I send email to other friends accounts it doesnt count it as spam

Well, I have used SMTP.XNET.CO.NZ for years and never had the slightest problem with my e-mails ending up in people's Spam Folders.  Maybe it depends on the content of the messages you are sending Wink

I find that spam filter blocking is relativly good these days, (back in th eday it wasnt that good) like if I send a bunch of links to a friend then it will be put in there spam box, otherwse it tends to be all good.

Things are good these days..... Except for power usage...............but thats a differant story... (as seen in differant topics)
