Mail Not Working

[vashil_mru]

Hello,
I cannot send mails from the server. I run the 15.5.15502 free version with the default smtp server.
When i click on the test button (settings->email), i get a positive reply : Mail sent. However none of them get delivered.
I also try sending the welcome email with the same problem.

I tried running a tcpdump and filtering on smtp, no packets turned up

On my firewall i cannot see any smtp traffic either.

Can you help?
thanks.

Hi,

Can you try using a different email address with a different domain name? (i.e. a GMail, Hotmail etc). Let's verify that it is not something related to the destination email first. The system will say "sent successfully" if it leaves the PBX, but it does not necessarily mean that it will be delivered to the destination if the destination has an issue or if something was mistyped.

Note that the system will use whatever email you have under Settings>Email>Notifications

Let us know how it goes

it works well with hotmail as destination mail for example.
what could be the issue?

Ok at least we know that your pbx sends the email, so if you cannot receive on a specific address I would think that there is something that blocks the email from being delivered (i.e. you provider may block it, or maybe a blacklist is preventing the email from arriving, or some other unknown factor). If you need to deliver the email to that specific address however, it may be best to use your own SMTP server so that you can have more control to debug the mail delivery.

You can also contact our Support Team for this issue at https://www.3cx.com/contact-form/ and select PBX Express (Cloud Instances) category when you report this to reach the appropriate department.
