Strange folders

[Marti Markov]

Hi all,

I’ve been experiencing the “magical” creation of random folders on my mail server.

I managed to catch the creation of one last night. Here is the log:

Aug 30 01:38:13 mail dovecot: imap(f.lastName at domain.com): Debug: Namespace : /home/vmail/domain.com/f.lastName/Maildir/.wkkwgfrubwioniohkcyqttugdtdabuyn doesn't exist yet, using default permissions
Aug 30 01:38:13 mail dovecot: imap(f.lastName at domain.com): Debug: Namespace : Using permissions from /home/vmail/domain.com/f.lastName/Maildir: mode=0700 gid=default
Aug 30 01:38:13 mail dovecot: imap(f.lastName at domain.com): Debug: acl vfile: file /home/vmail/domain.com/f.lastName/Maildir/.wkkwgfrubwioniohkcyqttugdtdabuyn/dovecot-acl not found


I have substituted only the username and the domain name. The folder name is as it was created: wkkwgfrubwioniohkcyqttugdtdabuyn



There has been no activity logged on the exim4 side at that time. What would be the best course of action to determine what is happening?
