If your IMAP Sent folders are missing, subscribe to them again to make them appear.
How exactly you do this will depend on what email client you are using.
For example, to do it in Mac OS X Mail Client:
Can you confirm if you are using Mac OS X Mail Client?
Sorry for the delay.
I am mobile at the moment and I will see if another expert can reply to you on this.
Hello. My name is*****'m a certified computer professional with 15 years of experience. It would be my pleasure to assist you with this. Let's begin by taking at look at the email settings for each of your accounts. Pete provided excellent advice, and you should definitely follow his instructions regarding the proper setup of accounts in Mac Mail Client. However, something I freguently run across, especially in working with email accounts that people have had for a number of years, is that sometimes, the accounts aren't setup to use IMAP servers, but rather smtp servers.
Listed below are instructions for checking the email account settings.
Can you please check those settings and let me know the results when you a chance?
Regarding the wordpress, you will need to back up all of your setting and configuration files and create a backup of all of your posts, then install wordpress on the new website and import all of the old posts and settings. I will be signing out soon but I will be returning this evening. Perhaps we can work on this together then. I did see that you are in Denmark. Please let me know when it will be a good time for you (other than for the next 12 hours or so) and I will make myself available. Thank you!
Soren, when you were setting up your email accounts did you follow theses instructions?
I realize that you have El Capitan rather than Yosemite but the instructions should work El Capitan.
You are using the correct servers but we need to check and make sure that you're using the correct ports.
I couldn't tell from the screen shot.
