 * Hi Support,
 * We have strange problem in our website. When we check our logs we see that every
   email is send. But almost every day we suddenly get 20 mails in our inbox with
   the message: Could not open socket
 * Is this bad? And how can this be solved?
 * We have outgoing mailserver on SMTPS with 465 port.
 * Thank you in advance!

 * Hi Tim,
 * Thanks for your reply. We did a connection test and all rules were green.
