 * I´d like to use the plugin with a non-auth mailserver. So there are no credentials
   and this is fine, as long as the mails are sent to my own mailadress. But greylisting
   might be an issue if the webhoster ip might change. Is there any kind of feature
   that deals with this? Like a re-try function (in the Pro Version)?

 * Hello [@cit1000](https://wordpress.org/support/users/cit1000/) ,
   Thanks for reaching
   out. As you’re asking about a paid version of WP Mail SMTP, could you please 
   drop us a line through our [contact page](https://wpmailsmtp.com/contact/) when
   you get the chance? 
 * You’re welcome to just include a link to this post, if you’d prefer to do that.
 * I apologize that we’re not able to respond to paid version questions here in 
   the WordPress.org support forums for the free version, but I really appreciate
   your help!
 * Thanks 🙂

 * No, i was asking about the feature itself. A resend / retry function. And IF 
   there might be a feature in the paid version – i´d buy it. You might call it 
   a pre-sales question. 🙂

 * Hi [@cit1000](https://wordpress.org/support/users/cit1000/) ,
   Thanks for writing
   back. For the presales question as well, we recommend writing to us directly 
   to comply with WordPress.org’s policy. In the meantime, I’d like to inform that
   we don’t have an automated resend/retry feature, but we have a manual resend 
   feature as outlined [here](https://wpmailsmtp.com/docs/how-to-resend-emails-in-wp-mail-smtp/).
   Thanks 🙂
