Cannot Verify Server Identity
When connecting to your email, the iPhone forces a secure connection for its initial connection attempts. If your domain is using a self signed certificate, you may receive a warning similar to this. This means that the SSL encryption for the domain is not registered with a company that issues SSL certificates.
It’s important to note, that while you can avoid seeing this warning by forcing the iPhone to connect with unsecure connections, you are only using a less secure connection in a way that does not resolve the issue.
The recommended resolution for this error is to accept the certificate as a trusted certificate:
- When you receive the popup with this error, click Details.
- On the next screen, click Accept.
You should now be able to access your email.
Cannot Connect Using SSL
If your domain does not have an SSL certificate and if you are not using the server name, you may receive this error. To attempt to proceed with the settings you have already provided, you may attempt to connect without SSL:
- From the error menu, select No, you do not want to try setting up the account without SSL, and then tap Save.
- Tap the email account you just attempted to set up, and then scroll down to tap SMTP.
- Tap the Primary Server.
- Tap OFF to turn the SSL setting on, and then tap Server Port to change it to 465.
- Tap Done.
- Tap AT&T SMTP Server and then tap OFF to turn the server on.
- Tap Done.
- Tap Account Info, and then tap Advanced.
- Verify the incoming Use SSL setting is set to OFF.
- Tap Account Info, and then tap Done.
If your settings are correct for reaching your server, you should now be able to access your email.
I Cannot Delete Emails
By default, iOS attempts to delete IMAP email by putting it in the phones trash. This causes an error to come up saying that the messages could not be moved to the trash folder.
To fix this:
- Go to Settings > Mail, Contacts and Calendars > {your email account} > Advanced.
- Select Deleted Mailbox.
- In the On Server section, select the Trash box under the server. This will allow you to remove email from an iPhone or iPod.
Too Many Connections – 500 Errors?
On the iPhone there is a function called “push,” and when it is enabled it keeps the connection to our server open and continually checks mail. Consequently, this creates many IMAP processes and eventually conflicts with our Terms of Service.
To avoid running excessive IMAP processes, you can disable push when you don’t need it.
- Go to Settings > Mail, Contacts, Calendars > Fetch New Data.
- Toggle Push to Off.
Now, instead of retrieving emails continuously as they arrive, your iPhone will use the global Fetch setting to retrieve emails manually or at intervals.
