I can receive my mail messages, but can no longer send mail after upgrading eM Client a few days ago. ( I am now on v.9.2.1841) My last upgrade was around October of 2022, and I am not sure what my previously installed version was.
I see no reasonable explanation for this since my SMTP configuration hasn’t changed. The other thing is, that eM Client has verified my incoming and outgoing email account settings are “Ok”. I even receive the confirmation email to my inbox via eM Client Diagnostics from the very account that I cannot otherwise send mail from.
GoDaddy Pro Support, that I have paid for, has looked at the problem and claim my mail server is running fine with no errors. They have also looked at my eM Client configuration and see no problems with the set-up. Furthermore, I have been able to configure 2 other email clients to use the same configuration and can successfully send email from both of those clients without any trouble. (i.e. it is only with eM Client that I have the problem)
Since I use the account in question for my business, I have real problem with not being able to send email. This makes eM Client useless for me when sending cPanel email hosted by GoDaddy.
Even more interesting is that I am able to receive and send email messages with no problems from other cPanel email accounts that are not hosted by GoDaddy. So it seems, either GoDaddy or eM Client is at fault. Since the problem manifested just after upgrading eM Client, I conclude that my desktop mail client and not the mail server, is the culprit.
There are several other nearly identical issues that can be found in this support forum that do not appear to have a resolution. Though, only one of those issues appears to involve GoDaddy and the mail hosting client is different.
My question then is, “What changed in the SMTP functionality since October, when I previously upgraded my eM Client?” Certainly something seems to be different. If eM Client can answer this question, then I should have a reasonable chance to debug the problem.
