similar to: imap webmail client needed

Hi all, As the resident Linux guru, I've just been tasked with costing a webmail setup for about 600 000 users. They each have 10MiB (small, I know) mailboxes. The current setup has about 40 million web page accesses per month. Has anyone here any experience with this kind of thing? If so, any pointers as to software and hardware used, and any other advice would be appreciated. TIA --

Just wanted to get some thoughts from the list..... We are a public k-12 school and are looking to migrate to a groupware style system for out staff to collaborate better. Currently we are using Squirrelmail/postfix for email. Does anyone have any recommendations/opinions. Any input would be greatly appreciated. Thank you -- Bo Lynch Systems Administrator RedHat Academy Instructor Energy Manager

Hi list, just for my appreciation: can I plug two harddisks already setting up with lvm into several boxes without losing my logical volume? Cheers, Kamill

Hello, Do you think Dovecot could handle millions of active users in a big architecture ? This cluster could be for example (each server is a bi quad Xeon 2.66 Ghz) : - 40 Dovecot servers - 4 LVS - 20 Apache+PHP - 2 Openldap - 20 Postfix + ClamAV + SpamAssassin - 1 NFS Netapps For millions of user it could be multiple different clusters of 40 Dovecot servers with 1 Netapp for each cluster. I

Hi Friends, I am planning to upgrade my mail server from CentOS4.5 to CentOS5. By this, I also planned to replace my postfix mail server with Scalix although the community edition limit me to just 25 premium user, I think it is suffice for us with the remaining user as standard user (with approx. <> 100 users total). Is there a catch on using Scalix based on your experience. I see that

Hello Everyone, I was using OpenGroupware but just hosed my system. Since I'm starting from scratch I would like to know what everyone's using for web based mail.

I would like to move my postfix to a chroot but have

I want to seriously work with IPv6 and not have stray IPv4 functions messing with me. So in /etc/sysconfig/network, I commented out NETWORKING=yes. I have NETWORKING_IPV6=yes. In /etc/sysconfig/network-scripts I altered ifcfg-eth0, setting BOOTPROTO=none. That was enough for eth0 to only have IPv6 working on it (have IPV6INIT=yes and IPV6_AUTOCONF=yes). But lo had IPv4. So I commented

Hi All, Is anyone versed in Zimbra? I have most things working except some MTA issue. I tried posting on the Zimbra forums after reading the docs, but my post was labeled as SPAM and the moderators have not replied to my private message to get my post reviewed. Who uses this type of method for getting help anyway? Aren't the days of Bulletin Board BBS's gone? Anyway... I installed ZCS

I just need a simple server to support a few personal calendars and a shared calendar. Any recommendations for a CentOS / Apache based calendar server? -- Bowie

Now that I have a working kvm setup, I thought I'd finally try how Zimbra works. This is mainly some microbenchmarking, so it may not have much to do with actual performance in real life. Setup: - 1GB memory given to kvm (from host's 2GB) - Intel Core 2 6600 (kvm uses only one CPU) - CentOS 5 - 15GB qcow2 image on XFS filesystem - Zimbra 5.0 RC2 RHEL5 x86_64 - Dovecot latest hg,
