similar to: dovecot proxy, imapproxy, perdition . . . or?

Hi System debian 8.11 and dovecot-2.2.36.4 My webmail is roundcube with imapproxy. I have one problem. My dovecot servers is are in a cluster with keepalived like: dovecot1----VIP-IP--------dovecot2 All works fine I have a problem with imapproxy when a server dovecot1 had a problem (kernel panic sic!) Keepalived works perfecty and moved VIP to dovecot2 - all works fine for normal users but

The wiki <http://wiki.dovecot.org/PasswordDatabase/ExtraFields/Proxy> page says this: "The connections created to the destination server can't be TLS/SSL encrypted.". Hrmm. Right now, with perdition, I'm forcing the use of STARTTLS on the internal connections. I'd just as soon get rid of perdition (to have one less moving part in my architecture), but I need the

Hi All! I am working on a complete migration from an old solaris machine running Cyrus IMAP v2.3.14 and wish to migrate all users to a new ubuntu vm running Dovecot 2.0.19. What I have so far is a fully functional dovecot installation with LDAP / Dovecot SASL auth using Maildir++. My plan is to use Perdition IMAP proxy on a third host and migrate users a few at a time (see attached picture of

We are currently evaluating the migration from a proprietary, legacy mail server onto Dovecot for 20,000+ virtual domains. This is a big job and we intend to do it by initially proxying connections through to the legacy server, and moving customers over in batches by turning off the proxy feature for them. In the manual it states "This model is still a bit unfinished in current code"

Package: logcheck Version: 1.2.22a Severity: wishlist There is no support for imapproxy, and it would be a great help if it was added. Following are two sample lines from the syslog: Jun 11 09:36:55 MyHost in.imapproxyd[30845]: LOGOUT: '"MyUser"' from server sd [13] Jun 11 09:37:02 MyHost in.imapproxyd[30846]: LOGIN: '"MyUser"' (xxx.xxx.xxx.xx:yyyyy) on

hello everyone, first of all, please forgive my bad english skill, I live in France. On our "old" Dovecot 1.x architecture, we have NFS shares between the front servers (MTA, IMAP...) and mail storage server. I've read some wiki2 pages that present the new director and imap proxy. But I'm still don't see things clearly, so I post here to have your advices to set-up a new mail

Before I spend some time experimenting with what might be impossible, maybe someone can just tell me (either "how" or that it's impossible). I'd like to get perdition out of my environment (mainly to have one less moving part in my architecture). I'm looking at dovecot's built-in proxying. In my setup, I don't have dedicated front-end machines. A user can connect

We've been collecting some stats to see what kind of benefits UP/SquirrelMail's IMAP Proxy in for our SOGo webmail users. Dovecot is running in High-performance mode http://wiki2.dovecot.org/LoginProcess with authentication caching http://wiki2.dovecot.org/Authentication/Caching During the weekend two servers (webmail3 and webmail4) has been running with local imapproxy and two servers

Hi, I'm planning on a new mail infrastructure which constists of multiple 'frontends' running webmail & public access pop/imap, which would communicate over imap/pop to 'backend mail stores'. My original idea was to run dovecot on the backends, use a predition on the frontends to proxy imap/pop and also run imapproxy in front of webmail [squirrelmail]. I've since

Hello, I've just finished transiting our proxies from perdition to dovecot (2.1.7-7 Debian). Yesterday 12 messages (all within the same second) like this caught my attention: --- Apr 25 17:19:09 pp11 dovecot: auth: Warning: proxy(redacted at gol.com,xx.xx.xx.xx,<26hUEivbfQBlMrMS>): DNS lookup for mb04.dentaku.gol.com took 5.002 s --- Now this machine at that time was handling a load

I was reading "conf.d/10-director.conf" and it mentions Dovecot proxy. I've been using perdition in the past for my pop/imap proxying needs and wasn't sure if Director could also use perdition or if it only works with Dovecots proxying. Thanks!

Hello, b I have a situation were I want to be able to give teachers access to their Google apps for education email through Squirrelmail. The network that they are on blocks gmail. ?? I am able to get Squirrelmail to communicate with Gmail via imap.? I am looking at getting persistant imap connections to improve the user experience.? I have looked at IMAPPROXY? but this application is not

Hi! I am about to migrate a perdition-based IMAP/POP3 proxy to Dovecot. Unfortunately some users are behind a firewall/NAT setup which throws away seemingly idle TCP connections sooner than the established default of 24 hours (more likely after 30 minutes ...) resulting in all kinds of weird client behavior. And unfortunately? this firewall/NAT setup is outside of my control and I have no means

I just migrated from courier-imap to dovecot and dovecot is a lot faster. My only client is webmail on the same server as dovecot. Max ~10 users. Should I still run imapproxy like I did with courier? Does dovecot periodically empty the trash folder like courier does? I reduced the number of processes courier was running to save RAM and improve performance. Are there any performance tweaks I

Is it possible to use Dovecot frontends in front of UWash backends? I need a proxy pool ASAP. There is not sufficient time to migrate the backends for 40,000+ users so they have to stay UW for now. I have been looking at Perdition but concerned about performance under load. Dovecot looks really promising with it's non-forking mode. I need simple dumb frontends no local mail. Other

Hi, I am testing dovecot with Outlook Mobile 5 (OM5), which is currently not working. OM5 connects, says "NOOP" and "CAPABILITY", does login correctly and simply loggs out after that telling the user that it could not download any messages. When I put an imapproxy[0] in front of dovecot, OM5 works perfectly well. That leads me to the thought, that something in the way dovecot

Timo, Is the director proxy inactivity timeout configurable? I just recently attempted to switch our production webmail's imapproxy system to use a pool of two directors and ran into problems with it apparently disconnecting them unexpectedly. I don't believe that it IDLEs, I think it just UNSELECTs to reset the state and then keeps the connection open until it's used again, or until
