similar to: Advice for new dovecot / imap proxy? setup

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 --

Hi All, I have migrated from uw-imap to Dovecot for POP3 & IMAP service. I run webmail using squirrelmail. When running uw-imap I used to run up.imapproxyd on the webmail server for faster responses. After migrating to Dovecot, I find that up.imapproxyd does not work well with dovecot. I tried to use dovecot as IMAP PRoxy server as per the document

Hi, I will probably have to design an e-mail (and other components) infrastructure for a small ISP soon (WISP). I'm doing some research to determine which components would be best to offer e-mail services to their client and allow the staff to manage accounts easily. I usually use virtual machines a lot for isolation and easy backups and migration (when a hardware node is

Do you see a use for an IMAP proxy where the proxy would be able to execute hooks which modify mail contents, such as transparent encrypting/decrypting mails, or maybe some virus-filtering? It would need at least some kind of IMAP command/reply parsing capabilities, so it might be able to do all kinds of other things. Maybe one potential use case would be Cyrus Murder-like proxying to multiple

Hello list, OK, I just registered with the list, so please be tolerant :-) I've been using another MTA for about, oh, I'd say nine years now. Due to reasons beyond me (mainly my clients demanding more for their buck / things like webmail etc.), I was forced to start searching for (always) open source alternatives. The last MTA was only POP3/SMTP. It does no webmail. It interfaces with

Hello...I'll TRY make this short. This post is not specific to Dovecot...but many subscribers to this list have probably been down this road. (private replies welcome if you want it to go off list) I currently use Sendmail with MailScanner, SpamAssassin, ClamAV, Procmail, and qpopper for POP3 (hash mail dirs for mbox files)on RedHat 9 server. Roaming users currently only have the option of

Hey all, A few minutes ago, I installed Dovecot, hoping things would get clear by just looking at the relevant config files, but since they don't, I hope someone here could give me a clue... What I want to achieve is really only basic functionality. It's just for personal use, so it shouldn't get too complicated. Up til now, I have been using fetchmail to get my mail off of several

I configured Dovecot on our mail server under Centos 5.3 (I think) some while ago now (about 2 years) and, to the best of my knowledge,it had been working correctly all that time. However, one of the team wanted to use webmail while away from base and found that, although he could receive emails OK, he was unable to reply or send fresh emails. When he pressed Send he got a message ?Authentication

The documentation says the bridge will work as far as all interfaces have the same MTU, but I also read on this and other mailing lists people having problems when using jumbo frames. What is the current status of jumbo frames support in the bridge? It could also be useful to have the same info on the wiki page. Thanks. -- Luca Lesinigo -------------- next part -------------- An HTML

Hi, after my publisher has to shut down his business at the end of last year, it took several months to organize everything. But it's done! I'm happy to announce: The Dovecot book is available again.

Hello, I'm a developer on the Orbited project (http://www.orbited.org), which provides a TCPSocket interface in javascript (emulated over HTTP using ajax and comet.) This TCPSocket allows true bi-directional communication between a web browser and an arbitrary tcp server. One of the other developers pointed me to a recent dovecot thread about webmail. Sorry for the new thread (I just joined

Hi, just a short question: I have installed and configured z-Push to use BackendIMAP. On my iPhone I have created an account and I can see my mails. Also sending works. So far so good. Now the question: When I create a new folder i.e. Test under the root (/), then I get an error. And after resyncing the folder has been created not under /, but under /0/Test. Also I can not remove that folder

I'm using roundcube webmail managesieve plugin. Webmail can login managesieve to a specific mailstore successfully without proxying.

Hi Timo, There was another thread (it has come up at least a few times in the past few years I've been lurking) on the postfix list about having some kind of automatic 'Save to Sent' option to avoid the users mail client from having to upload messages twice (obviously the only ones of concern are ones with large attachments) - once to send it, and once to save the copy in the sent

Trying to figure out Proxying with LMTP to a few back end storage servers for quota checking before accepting email delivery on the front end nodes. If I connect to the back end server directly via telnet, everything works great. If I use a front-end server to proxy to the back end server, I don't get the same result. Running 2.2.4 on both front and back end servers. Any help would be

Hi all, Out IMAP client (Outlook and others) use login name like joedirt at domainname.com I need dovecot to convert it to joedirt-domainname_com since that is the local login name.

Hi List! I have an issue with dovecot: Outlook express users sometimes can't see some emails (they are not even listed) that can be seen with other IMAP clients, I tested it (and it works) with Evolution, Outlook and SquirrelMail (a web mail). Please note that this is not the client bug reported at http://dovecot.org/clients.html with the message: "Message is no longer available on
