no confirmation e-mail sent since update 4.6.8?

[Anonymous]

Hi there,

I’m not 100% sure, but it seems that since the update 4.6.8 the people registering for the newsletter through the website don’t receive the confirmation e-mail anymore (yes, we even checked the spam folder…).
We didn’t change anything else lately but only did the update of the plugin.
Anyone else having this issue?

Any comment appreciated.

Best wishes

That is rather strange, can you do a test from the diagnostic panel?

Dear Stefano,

thank you for your reply!
Well, I tried it with the diagnostic panel this morning where it said OK. Now it says:

Email sent with WordPress: FAILED (Could not instantiate mail function.)
Email sent with Newsletter: FAILED (Could not instantiate mail function.)

I also tried with a different e-mail address in the general settings (not the same domain name within the address) but it did not work at all.

Here is some content from the return to sender error:

Temporary MTA failure on relaying, From MTA() during
fwd-connect (All attempts (1) failed connecting to smtp:*:10025)

I have no idea if the message tells you something…

Best wishes

Open a ticket to the provider, the PHP mailing layer is broken in your server!
