and on php list i got a message like sent failed…

My ses config:

AWS access key ID
AWS secret access key
SES endpoint
Whether to use curl multi to send emails concurrently
The maximum number of emails to send concurrently when using curl multi, (between 2 and 32)
Whether to create a log file showing all curl multi transfers
Whether to generate verbose curl output (use only for debugging)

and you want know one weird thing if i put to YES this parameter : Whether to use curl multi to send emails concurrently i got success message but in real no email is begin sent … even from AWS control pannel i see 0 email sent

what can be i checked logs and config but not able to find what wrong

Something must have been changed either by you or your hosting company. What is different about this campaign to the previous ones?

Is there any information on the phplist event log page?
