Hi there.
I hope there is someone out there who can help :X3:
I administer a site hosted with VOX. I had a website form which uses a basic "sendform" php function. This worked fine until 2 weeks ago when it suddenly stopped. (The form was not developed by me.)
I have tried everything I know (which is not a hell of a lot) to fix it and even installing a Joomla site but to no avail, no forms worked.
Any ideas what the issue could be?
VOX does not seem to be able to help..
 
First thing to check is which SMTP server you are using to send email from the site and if that server is still working, and if the credentials to authenticate to that SMTP server is still functional..

Test from elsewhere to the VOX server.. if still working off of vox, vox may be blocking the connection or the SMTP service provider blocked vox server IP addresses..
 
I'm unsure how I can test but mail server seems fine (using smtp.voxtelecom.co.za) as my clients email uses it ok.
The form is on same server and phpinfo says smtp: localhost and smtp_port: 25 - is this correct?
 
Next best bet is to add logging to your php mailer function and work from there to resolve the issue..
 
Obtain your public IP by using any of the free tools available on the 'Net, for example checkmyip.com

Then go to https://www.spamhaus.org/lookup/ and lookup your public IP if it is on a blacklist.

If not, then you know the problem must be on the server.

If you're blacklisted, then check out why. Maybe somebody managed to haxx0r your server and get it to spam other people's email servers. if this is the case, you'll need to address and resolve this issue first as subsequent removals and additions to the blacklist will only result in your public IP getting permanently blacklisted.
 
Box should definitely be able to help if they host the site and the mail server that it’s sitting on... there’ll be logs either within the php error log or the smtp server log showing why transmission was rejected on smtp or reason why delivery did not complete.

If they can’t help then it may be time to move
