Note: we have seen a handful of reports of slow Webmail performance; those servers are completely separate from the cluster, so if you are seeing Webmail performance problems, please note the time it occurred, the error you saw if any and send an e-mail to .

  6. Isn’t there an app for that?

    I’m unaware of any immediate plans to produce any smartphone screenshots for mail configuration. From my limited experience with those devices, all you need to know is your email address, username, password, that our IMAP server is named and that our SMTP server is named

  7. Well, my main problem has been not being able to delete IMAP emails from my iPhone. I wanted to make sure my port settings were all correct to see if that corrected the problem. Otherwise you’re right, the settings you describe work great. Thanks.
