Welcome email not sending

[Mike Langensiepen]

Hi, I've just set up a trial of PBX Express. It passed all the tests including outgoing mail when setting up However, from the control panel, it's not sending the welcome emails and when I try the SMTP test, the button just blinks and gives no errors.

I've verified the email account is OK by sending from an existing machine.

Anyone got any ideas?

Thanks

Hello @Mike Langensiepen

Did you set the PBX express on the google cloud? If so please note that google blocks the standard SMTP ports for standard ports as mentioned in the end of this guide: https://www.3cx.com/docs/hosted-pbx-google-cloud/

Try setting up a gmail account following this guide: https://www.3cx.com/blog/docs/gmail-mail-server/ to test that everything is ok

Thanks for the reply. I did set it up using Google Cloud but during the setup process I also got the standard SMTP test reply:
SMTP Test OK - your PBX can send emails
Nevertheless I'll try it with a gmail account. Many thanks.

Grrrrrr. I set up on gmail as suggested (shouldn't be necessary as my smtp runs 587:TLS as well) and the SMTP test messages come through OK but I am still not receiving welcome emails. I have checked spam folders etc. Any ideas please? I feel like I am failing at the first hurdle.

Could it be that your receiving SMTP blocks the attachments? Have you checked that possibility?

 

[Mike Langensiepen]

I wish it were that simple but I have whitelisted the sending email address and also sent to outlook.com, gmail.com, our domains on different email servers etc. I have checked the webmail logs on our own email server (SmarterMail) and there is nothing to suggest that the welcome email is being blocked.

A change today though - trying the smtp test again, I get this message

• AuthenticationInvalidCredentials: 5.7.8 Username and Password not accepted. Learn more at 5.7.8 https://support.google.com/mail/?p=BadCredentials u29sm6804301pfa.15 - gsmtp

The crdentials are definitely correct and I have re-entered them to make sure. The weblink provided gives no hint as to the issue

 

[Mike Langensiepen]

Re-entered everything and the tests are working OK again but still no welcome emails



Edit: I'm now using the same email account for sending as an extension that I'm trying to get a welcome email for. Still nothing coming through.

I've noticed that when I exit the email settings and then go back in, it does remove the :587 from smtp.gmail.com though

 

[YiannisH_3CX]

The port is auto removed because 587 is the default port when you enable SSL/TLS so it does not need to be present in the email settings.
If you choose a different port then the port will remain visible.
Have you enabled Allow less secure apps from the gmail settings as mentioned in the guide?

 

[Mike Langensiepen]

Yes, I have enabled the Allow Less Secure Apps option. I followed the guide exactly.

Have you tried using gmail as your smtp server and the recipient of the welcome email is an email address other than your domain? Add an extension that uses a gmail for example. Do attachments arrive then?
That will help you narrow down where the issue comes from.

We used Sendgrid in a separate VM for this and it works a treat.

I've used gmail and SmarterMail (our standard email server) for smtp outgoing. I've used gmail, SmarterMail, Outlook365 and other email addresses for incoming. NOTHING arrives in the inbox and I can find no evidence that 3CX has sent the welcome email.

We use SmarterMail extensively and I have never had a problem with incoming or outgoing emails on it. We use TLS/587 as well as plain 25 for outgoing and 995/SSL for POP (along with less secure 110) for incoming and I whitelisted the 3CX address in SmarterMail. There must be something fundamental I am missing as I can't see why this is such an issue.

I am completely at a loss!


Alex, our SmarterMail supports outbound authentication from any carrier but we have a legacy server that we use hmailserver on for when we need sending support for Office 2003 (which a few of my users are still on) - that company uses Office365 mailboxes and that requires TLS which Office2003 doesn't have. We are looking at Stunnel though which might be a simpler option for this..

 

[Mike Langensiepen]

OK I found the reason why. You have to go through the phone provisioning for each extension even though I don't select a hard phone. Once I do this, cancel the hard phone selection and then click OK, it then sends the welcome email.

Silly me for assuming that because an extension showed 3CX client under phone provisioning that it was active.

Many thanks for all the suggestions!
