Thanks, I've read through that document a couple of times now & I'm fairly sure my system 'ticks all the boxes' yet the warning messages continues. I can see no noticeable time discrepancy when I do periodic time checks from the command line comparing against another system's clock - certainly not 2 minute error margin Could this be a time mismatch between imap client & server?

[Dovecot] email addresses as usernames with Kerberos
by Peter Mogensen 14 Jan '11

14 Jan '11

Hi, I was trying out Kerberos authentication with som sample users for Dovecot and stumbled into this problem: The user names are of the form local-part@domain, so the Kerberos principal becomes "local-part\@domain@REALM". But it seems Dovecot (1.2.9) doesn't understand that syntax. Looking at the 2.0.8 sources I guess it's not supported. But isn't this a valid Kerberos principal? Is it a bug, or a missing feature or is there a special reason for not supporting it ? kind regards, Peter

Running Dovecot 2.0.8 on 32bit Centos5.5. The machine is a VMWare ESX VM.

Has anyone else encountered this message? Is it something to be concerned about? Thanks, Ian.

Re: [Dovecot] Making shared folders "unmovable"
by Dave 13 Jan '11

13 Jan '11

Well, I just noticed this in my logs after I re-loaded the latest Dovecot config I tried: Jan 13 15:09:45 mail dovecot: SIGHUP received - reloading configuration Jan 13 15:09:45 mail dovecot: read(imap dump-capability process) failed: Interrupted system call Jan 13 15:09:45 mail dovecot: Invalid configuration, keeping old one Jan 13 15:09:45 mail dovecot: child 2085 (unknown) returned error 82 (Internal logging error) It's apparently been doing this every time I've reloaded the config, so this is probably why none of my changes with the ACLs are working. :/ Any thoughts on what could be causing this kind of error?? Does that error just basically mean something's set wrong somewhere in dovecot.conf? David

I have indeed worked with VM infrastructures using SAN storage, and yes, it's fantastic. Just this particular location doesn't have a SAN box installed.

The 3.x branch is rock solid. There have been no crashes (yet!) Would DRBD + GFS2 work better than NFS? While NFS is simple, I don't mind experimenting with DRBD and GFS2 is it means fewer problems?

[Dovecot] Denying authentication
by Romer Ventura 13 Jan '11

13 Jan '11

Hello, I've been running dovecot for over 3 years now and it works with no problems. I have it setup so that it authenticates users against Active Directory via LDAP and so far no problems. What I would like to know is if there is any way that I could deny access for users trying to access email via cellphones or email clients outside the company. I can close everything since there are a few users that need to get emails from outside the company via cell phone of email clients. I was thinking if there was a way to lets say create a group in AD named: "remote-email" that will allow connection and authentication from any network, any user not in that group will only be able to authenticate if the source is 192.168.xx.xx/24. Is this possible? Maybe not with Dovecot, but maybe someone else has any ideas..? Thanks -------- Romer Ventura

[Dovecot] Making shared folders "unmovable"
by Dave 12 Jan '11

12 Jan '11

I have set up an area of shared folders with Dovecot 1.2 that is accessed by several people (by way of one account, and everyone who logs in sees these same folders), and the only problem with this setup is that occasionally somebody moves one of the folders underneath another folder or somewhere else in the folder structure, and this sometimes disrupts some automatic procmail filters and the like. Is there a way to keep folders in a shared setup such as this "static" or "unmovable" so that the users can't disrupt the structure? Like, where the folder structure itself can't be changed, but new messages can still come in to the folders? David

[Dovecot] How do folk . . . Aggregate system mail from LAN machines?
by Ron Leach 12 Jan '11

12 Jan '11

List, good evening, Running Dovecot for external email, but not yet worked out how (best) to aggregate 'system' mail from other machines on the LAN. By system mail, I mean mails generated by the OS or by applications, and addressed to root, or 'some admin user', etc. Ideally, these would be seen by 'root' or 'some admin user' or whoever on our existing Dovecot/IMAP system. Our scale is not large, we only have 5 servers on the LAN doing various things. I wondered how other Dovecot users do this. I've thought of 3 possibilities: 1. Install Dovecot on each LAN machine, and use Fetchmail to retrieve the messages using POP so that local mail stores were emptied. 2. Perhaps, use a 'forwarding' mechanism of some sort on each LAN machine, but that would require an MTA on each LAN machine, would it not? 3. I wondered whether /etc/alias, mentioned in a recent post by Simone Caruso, might help though again, presumably, requiring an MTA on each LAN machine. What do you do? regards, Ron
