i can send no massenges

I am experiencing the same issue. Plugin has been updated and receiving error message when trying to send: Failed to send your message. Please try later or contact the administrator by another method.

Thanks for your help in advance!

Though the plugin successfully sends millions of emails every day, there are a host of issues that can stop or delay emails on both the sending and receiving ends. It depends entirely on your local Server & WordPress configuration. You will need to investigate this issue for your particular local configuration.

See Contact Form 7 Email Issues. There is a link at the bottom of the page to a comprehensive and detailed article which covers many issues. Most people that work through this information appear to be able to resolve their email sending & receiving issues.
