Thank you, @shawon001, for your quick reply and for the link.
I have confirmed that there are no firewall or other plugin issues, and that curl is up to date. Although it is true that the host’s configured timeout is fairly low, all other site functions are working as intended; it is only requests sent from WP Mail SMTP which are timing out.
Because the server configuration works as desired otherwise, I am wondering if it is possible to pass a custom timeout parameter to the plugin. Is there any interface to do this, either in the admin panel, or via a filter or similar?
Thank you!
