Email configuration working and not working. Agh!
I've got to the point where I need to bother you good people! Here's the situation I need help with.
Added newdomain.com.
Created three new mailboxes.
Emailed out the mobileconfig files accordingly.
The configuration works on iphones and on a Windows VM I spun up to test things, but not on my Mac or the domain owner's Macs. (That may or may not mean it's a Mac thing?)
I have tried Mac Mail, Thunderbird, and Edison Mail, the error reported from the latter being:
[QUOTE]Authentication failed. Your email provider have [sic] blocked this account from login through this method. Please check your provider account/security settings (IMAP).
I wondered if the IP addresses had been blacklisted per this thread. My provider does not use cPHulk, but csf and Imunify360, and assures me that the IPs are not blocked. In short, I can't think what else might be going on, so thought I'd turn to some collective intelligence here if you will be so kind. Help.

Hey there! We'd need a bit more information to be able to provide you with some thoughts. If it helps, most of us on the cPanel side of things use Mac, so it's likely not a Mac-specific issue. I've personally used Mail and Thunderbird with cPanel servers for years. When that message appears in the mail client, do you see anything happening in /var/log/maillog on the server? That would show authentication attempts to the mail server and may give us more critical information. 0 -
Thanks @cPRex. I too have had no problem in the past with other domains using Mac mail clients with mail configurations offered by cPanel. This wouldn't be so embarrassing if I was just a complete newb!

Same mobileconfig as for the iPhones happily authenticating, so same password.0 -
Thanks for that. And just to be sure, we're certain the account/user is not being blocked in CSF or cPHulk for any reason? Those really do look like bad client setting errors, though, which is odd since you've tested with multiple clients. In our guide here, it sounds like you're the second option, "all email accounts on one cPanel account" 0 -
That's a neat list. Thanks. Let me go through it with my webhosts and see if there's anything in there we haven't looked at. 0 -
My webhosts checked out the troubleshooting list and couldn't find anything. They proposed trying a different setting for the incoming mail server " port 143 and STARTTLS instead of port 993 and SSl/TLS. But that made no difference. They've just sent me a log for a 24 hour period. Can I upload that here to see if anyone can spot anything I can't? I just tried to attach it, a .txt, but the file is greyed out when I try to attach it. Perhaps it's not an allowed format on this forum? 0 -
It's odd that the host couldn't resolve the issue. If that's the case, they always have the option of reaching out to us directly as well. You're welcome to paste the log here, but please change any public domains or IP addresses. 0
