<![CDATA[What is the intention of /home/yellowtent/boxdata/mail/spamd ?]]>I was just browsing around the file system out of curiosity and interest, and found /home/yellowtent/boxdata/mail/spamd and didn't see any references to this in the forum or documentation so figured it'd be a good chance to learn how that part of the Cloudron server works. I assume this is where SpamAssassin does it's learning from Spam mailboxes and stores it's Bayes tokens and such?

In my case, I saw a ton of folders in there and oddly enough for many mailboxes that don't exist such as my username@differentDomain.tld and I suspect this may have to do with a long time ago when I setup a bunch of aliases in Rainloop to quickly switch to different domains hosted on my server for postmaster/webmaster, etc. I changed tactics a long time ago though and so unsure if this is just old left-over cruft. And if so, is it safe for me to remove those to clean it out a bit?

Many (though I don’t think all) of the email directories that are unexpectedly found in this directory are from mailing list addresses. In other words they are on the recipient list of a mailing list.

So it’s as if the mailing list feature is creating these too, but it doesn’t make sense of course to have one on the forwarding addresses. The mailing list email I could see and understand I guess since it’s still trying to identify spam to not forward, but I don’t get why it’s adding the destination addresses in as if they’re mailboxes that it can learn from.

I can’t reproduce on-demand that I’ve seen so far but just giving it time for a day or two and they’ll start to appear. I guess sending an email to the mailing list would trigger it, I can try that too next time I’m at my computer again.

I think if you can send emails from those yahoo/gmail/me accounts and if they somehow create those directories, would be great!

Do you happen to use email lists feature? Not sure if it's related but that is one feature, we don't use and neither do I use in my personal server.

It's something very strange for sure. Maybe something unique to my environment if you're not seeing it at all, but I'm at a loss to what creates it since I am not manually creating any directories so it's presumably Cloudron creating that content.

That one is safe to ignore.

I went and checked some of the mail servers we had access to and they don't have external mailbox directories there. Is anyone else seeing this?

No idea how they're getting created as I've never hosted some of these mailboxes before and the domain isn't one I host either.

For example, these are forwarded addresses (from a mailing list) being listed in the directory:

drwx------  2 cloudron cloudron 4.0K Mar 13 05:59 {redacted}@yahoo.ca
drwx------  2 cloudron cloudron 4.0K Mar 13 06:17 {redacted}@gmail.com
drwx------  2 cloudron cloudron 4.0K Mar 13 06:21 {redacted}@me.com

There's also an unexpected one too...

drwx------  2 cloudron cloudron 4.0K Mar 13 04:57 shared-mailboxes.db

Just following up on this. Doesn't seem like it's been fixed yet. 😞

Anything needed of me for fixing this defect?

So definitely seems to be a bug. Is there anything I can do to help troubleshoot / diagnose it? Do you want SSH access again?

Here's a screenshot showing some of the mailboxes in the spamd folder, can confirm the @me.com in there which obviously I don't host that domain since Apple does. 😉

One thing I noticed is the permissions all seem a bit inconsistent, not sure if that's expected but I'd have assumed they'd be consistent. So that may or may not be another bug too?

So the @me.com address is only present in spamd. I've deleted it again from spamd and will see if it comes back again later today.
EDIT: I just looked again in the spamd folder and actually found three others in there that went to domains I've never hosted (i.e. they're external domains used in forwarding only from mailing lists and not mailboxes). Definitely seems like a bug, but I've removed all of them now and will see if any of those come back.

I’ll check the vmail too once I can tomorrow.

Can you remove it when you ssh in the next time around and let me know when it re-surfaces?

If you see anything not belonging to Cloudron, you can delete it . If they "re-appear", please report here, because that is some bug. I thought we fixed this bug a long time ago. I quickly checked atleast 5 Cloudrons that I could get hold of and none of them have external mailboxes (anymore).

It shouldn’t though as it’s an @me.com address (Apple-owned) so it’s never been something I could even host at all in the first place.

Though now that I think about it, back before Cloudron allowed mailing list to external addresses, it was a mailbox on their business domain and then a forwarding rule assigned to their @me.com address. But that mailbox was removed soon after mailing lists could forward externally and is just a mailing list since the. So maybe there’s still something in there?

I’ll update tomorrow 🙂

Do you know if this address was a mailbox before? If so, can you also double check if /home/yellowtent/boxdata/mail/vmail/<forwardingaddress> exists ?

For example, I have one directory created in there for an email that doesn't reside on my server and is used in forwarding only from a mailing list in Cloudron (not from a mailbox). Seems strange that'd be in there, no?

This can happen because of user action - user marked spam or ham (moving in and out of Spam folder). There is also nightly cron job that learns from recent mail (mail of last 3 days) of each user.

I feel less scared. haha. Still not sure when it gets generated though, I had tried for example moving one email to my own spam folder and checked but didn't see it generated. Any insight there?

For context: I moved all the files inside of that directory to /home/ubuntu/spamd-backup/ just so I had it in case I needed to restore. So the directory was then empty, and I restarted the mail service and it auto-generated the acl.cf and custom.cf files, but I don't yet see any user mailbox folders in there. Is that expected?

I'll just go ahead and empty that folder (minus a couple of mailboxes) to make it easier since it'll just regenerate what's needed/used too.

It has the symptoms you mention. You will see random addresses, cc addresses etc there. You can safely delete them, they won't reappear. If they reappear, let us know.
