Bit of a strange problem - can’t pinpoint the culprit.
I have been using MXroute account, haven’t changed any settings, nor passwords for months (strong passwords, lots of characters etc.).
Using Gmail mail client configured to send and receive email through my MXroute email works fine. So I suppose there’s nothing wrong with the MXroute service. However:
WordPress websites use Easy WP SMTP plugin for sending emails - configured to use MXroute SMTP. This doesn’t work!
Another plugin, “Newsletter”, used to send newsletters - is also configured to use MXroute SMTP. This plugin works and sends emails.
Tested these two on three websites, on two separate servers - with the same hosting provide though.
Hence - I suspected there must be something wrong with the Easy WP SMTP plugin.
On a third server, with a different hosting provider, I’m using another application - “Infinite WP”.
This application is also configured to send emails using MXroute.
And it doesn’t work!
If it weren’t for this - I would suspect the Easy WP SMTP plugin.
But because of this - I’m checking here with you. Two apps on different servers both started not working at the same time. That is why I think it could be possible there’s something wrong with MXroute.
Could you check? Or point me in the right direction?
I did ask one hosting provider’s tech support - wrote practically what I wrote here - asking them to check just in case. Got this reply (no PHP error log on the server as I had checked):
Possible causes would be the remote server you are trying to connect with in blocked in the firewall or a PHP coding issue.
We did some recent software updates, which included PHP updates, so that could be related. Trying checking the error_log for any related PHP errors.
If you can provide the IP or IP’s it may be trying to connect to, we can check the firewall on that server.
