Red Error sending emails

Hi There, I can see there are other responses for the sending email error.

We are on version 18.10.3 and this has just started happening last week.

I know the info said version 19+ no longer has inbuilt SMTP but we have not yet updated and getting this.

If we go to email settings and enter custom SMTP settings we receive a copy but the recipient does not get it (tested on external email). We will then be stuck between a rock and hard place.

Any suggestions??

Yes. Update your software. You are roughly 1,000 versions behind the times. The reason the feature has been removed is because it doesn’t work. This is not a case of it working on older versions. It doesn’t work on any version.

If you get a copy of emails sent, but your customers do not, that proves the email is being sent. In such a case, either your customer is blocking you or there is a problem with your email provider.

Hi Tut,
I’m a bit confused, I updated my desktop version a few weeks ago and have just read that emails are no longer being sent through Manager, but I sent one last night with seemingly no problem. I saw you stated that emails won’t work on any old versions?
I’m using outlook for my emails…
Any insight?

In the past it was optional to use an email server of your choice. Now it’s the only way. If you have already set this up you would notice no change.
