I'm trying to install a new mail server and I think I've done something completly wrong. I don't know how to fix/continue my current situation.

I've installed postfix on my Debian 11 system, working with virtual mailboxes. After that I installed Dovecot and configured it so that it get's access to the virtual mailboxes. But each time I receive a message, I get a message like this:

Jul 26 09:26:34 vps2412004 dovecot: imap(myuser)<31563><fGP3dV4BMvNSh3xC>: Error: Mailbox INBOX: open(/home/virtualmailboxes/myuser/cur/1690356394.V805I40085aM26143.vps24.fastwebserver.de:2,) failed: Permission denied (euid=1000(myuser) egid=100(users) missing +r perm: /home/virtualmailboxes/myuser/cur/1690356394.V805I40085aM26143.vps24.fastwebserver.de:2,, dir owned by 2000:2000 mode=0777)

When I look at the file, I see this:

-rw-rw---- 1 virtualmail virtualmail 324672 Jul 26 09:26 /home/virtualmailboxes/myuser/cur/1690356394.V805I40085aM26143.vps24.fastwebserver.de:2,

What do I have to do so Dovecot can access new mails properly? Right now I have a workaround (cronjob with chmod) working which can't be the real deal...

Please help!!

PS: I'm a newby...

Is the dovecot user a member of the virtualmail group?

Most people don’t grasp that asking a lot of questions unlocks learning and improves interpersonal bonding. In Alison’s studies, for example, though people could accurately recall how many questions had been asked in their conversations, they didn’t intuit the link between questions and liking. Across four studies, in which participants were engaged in conversations themselves or read transcripts of others’ conversations, people tended not to realize that question asking would influence—or had influenced—the level of amity between the conversationalists.
