Email campagin won't send (or queue all emails)

[lucakuehne]

I did change those things.
And I got the bad email address. The only thing which might cause an exception is a "é" in the email address... It is is a valid character, but it might cause some problems...

What mysql version do you have?

I'm running a MariaDB 10.3.16

Try to convert column 'lower' in 'email' table to utf8mb4_unicode_ci. Make a backup of the table just in case. This may take a while if you have a big table.

I changed the column 'lower' to utf8mb4_unicode_ci, but in the 'email_address' table and not in the 'email' table.
And that did the trick. The emails are now getting sent. :-)

EDIT: Sorry for the missleady typo! The emails ARE getting sent
