Re: imapd seems to serve up emails with empty attachments.
Hello Jeroen, When I get "empty attachment" from TB it usually seems to be some sort of time delay - the attachment hasn't downloaded to the client fast enough. But that would only make sense if the response time from one of your two folders was slow, which seems unlikely Chonny On 3/11/2014 5:44 AM, Jeroen Baten wrote: > Hello Willy, > > Since both messages are served up by cyrus I thought that would cause > the problem. > Just installed evolution and gave it a try. > > Damn, you are right! :-) > > Weird though.

Re: reconstruct
For what it's worth, we've been doing a reconstruct on the entire mailstore every night for the better part of a year, without ever shutting down cyrus. The reason is that we do a Trend Micro scan of the mailstore nightly - a couple of times a month that catches a virus which wasn't caught as the mail arrived (probably because of updated virus definitions). Anyway, whenever Trend quarantines a message then that folder is corrupted, and the reconstruct fixes that. Hasn't caused problems. That doesn't mean it's the smart thing to do, of course... Cyrus is running on Fedora Core 3 linux. Mailstore is 17Gb. Daniel Eckl wrote: Steve Huston wrote: On 9/21/06 5:04 AM, Daniel Eckl wrote: Hmmm yes, I want to second that.

Yes, that's my preferred way also. Just restore a complete folder, name it e.g. "RESTORED" or similar, put it in the mailbox root and make a reconstruct online. Then th euser can decide what to do with it. I think as well that this should be safe. Sounds very logically.

Re: mv virus infected mail files behind cyrus's back
We use both Trend Micro and Clamav to check mail on the way in. Then
overnight we have Trend Micro rescan the whole mail store. After that,
early in the morning, we run a scheduled reconstruct just in case some
messages were removed. We do detect things overnight that weren't found
on the way in, and its not always because of updated virus definitions.
We don't understand the difference, but it happens... That system has
worked well for us for over a year. However, most of our users are with
POP, and the IMAP users seldom use disconnected mode...

well, it's not really something you're supposed to do on a regular
basis ... a cleaner approach would be much harder to implement,
however. So if you feel you must do this, the "reconstruct" way should
be OK. Note that it may cause problems for IMAP clients that use
disconnected mode, because the UIDVALIDITY of a modified mailbox will
change, thus invalidating the client's cache.
We don't do anything like that. We scan for viruses when the mail is
delivered. Obviously not all are found, but I believe that you can't
get 100% protection. SO we try to educate our users to stay alert and
not to rely only on virus scanners. Modifying mail that's already been
delivered seems too intrusive to me. YMMV, obviously.

Re: "reconstruct -r" usage
Hi, Sort of a side note - we started having trouble like that. Turned out that our overnight antivirus scan of the mail store would find a virus, and quarantine (move!) the infected file, thus messing up the Cyrus indexing. Now we schedule a system-wide reconstruct after the virus scan, which seems to work. Back to the main topic, our cron entry (Red Hat Linux) is: su - cyrus -c "/usr/lib/cyrus-imapd/reconstruct -r user > /dev/null" and the "-r" does seem to work for us!

We've had the server lock up, and I'm suspecting that this might be part of the cause. (or perhaps it's a symptom? who knows) At least we never lose any messages.

Cyrus, Linux, and Anti-Virus
Hi all, We have Cyrus server 1.6 running on RedHat Linux 6.2 (on Intel). I'm wondering if there's an anti-virus client I could run on the server [in addition to hoping all the mail clients are configured to work with a local a-v program...]. It would have to be (1) on linux, (2) able to work with sendmail or the cyrus mailstore, and (3) not overly slow down a PentiumIII/600Mhz (with about 40 users). Come to think of it, it should really intercept incoming traffic (sendmail on our system) and not the cyrus mailstore, so it doesn't have to re-check everything for every log-on!!. Is any such thing available?? thanks, John Conant === [EMAIL PROTECTED]"An expert is a [person] who has made John Conant all the mistakes which can be made Aerodyne Research, Inc. in a very narrow field" (978)663-9500, ext. 292- Niels Bohr (Attrib.) ===
