similar to: Can Dovecot authenticate against an external email server?

Is it possible to run a bash script for authentication where a 0 exit code indicates success and a non-zero is failure? What I'm trying to do is create a shadow IMAP server that authenticates against a different server. That way my server will use the same passwords as an existing server. So what I would need is for dovecot to pass the username and password to my script, I attempt to log

Here's what I'm trying to do. I have a spam filtering operation as a front end for other servers. I've created a virtual server for spam storage where the user will be able to log in using squirrelmail/dovecot to review and release their spam. The email is stored in maildir format. Piecing it together I can use squirrelmail to pipe the email into something so that if a use finds a

Not directly Dovecot, but a configuration problem. We have a working set-up with Dovecot+Procmail+Sendmail, using POP-before-SMTP. We want to be able to offer email accounts to some local schools, using SquirrelMail (keeps their costs & maintenance down). The whole arrangement is working, but we don't want to have to have 300+ School children as users of our Red Hat Enterprise server,

Hi I'm using dovecot imap with ldap accounts. User management interface is phamm. Internal clients connect directly using imap client. External clients must use webmail (squirrelmail). But not everyone is supposed to use webmail. Is there any way to control who is allowed to log in from a specific IP (webmail ip)? Thanx for suggestions Jan

Hello List, I just installed dovecot and i love the simplicity of the default config; it simply works. Now I want to setup and web-based in addition to the default pop3 and imap client access - what u guys can recommend? Thanks. str

Some time people running Squirrelmail get connection dropped by imap server. Anyone know what causes this? Thanks in advance.

This is probably easy but how would a set a secret static master password so that if I typed it in for any login it would be happy? I can't use the * separator method in this case because it screws up squirrelmail.

Every once in a while I get this [1] error when trying to open a mail folder in SquirrelMail. I don't know enough about IMAP to tell if it is a SquirrelMail or a Dovecot issue. I also get this [2] error message every time I try to send an email. The email goes through but there is no copy in the Sent folder. If there is some kind of logging I can enable that would help with this please let

However when I try to delete an email in my Inbox, it doesn't get deleted.? It only sends a copy to the Trash folder.? But the

Hi all, I have recently switched over to Dovecot from CourierIMAP trying for some speedup, which I did get. Installation went OK, so all seemed fine. But suddenly I realised, that incoming emails are replicating themselves. This seems only to happen when connected with Thunderbird. I am also using Squirrelmail and KMail as clients which don't seem to show the behaviour. It seems to

Here's a kind of "outside the box" thought. Why not extend the IMAP protocol to send email? Instead of having to use SMTP if an addition were made to the IMAP protocol then IMAP could transport outgoing mail to the server the same way it moves messages to the server. On the server end Dovecot would deliver outgoing email to the host MTA via localhost:25. The advantage would be

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

Got sort of a strange problem on one email account. Everything works fine with Thunderbird/IMAP showing the correct unread message count. But on my DroidX smartphone one of my email accounts always shows one unread message, but I can't bring any unread messages up. It's like there's something there making it think there's a message when there isn't. The email client is K-9

Dear Dovecot experts, I have a small home server debian based, with postfix/dovecot/squirrelmail installed locally and working. Dovecot is used non-secured (no imaps) but only on the 192.168.0.100 address (address of the server on the local network). I want to use squirrelmail to read my email from outside. Squirrelmail can configured to access it in particular, either through cram-md5 or login

I'm advocating for a change in the IMAP specification to allow outgoing email to be sent over the same connection as incoming rather that having to separately configure outgoing SMTP email. There are two significant advantages to this concept. 1) It would greatly simplify setup for clients as they would only have to configure one connection rather than two. 2) Spam reduction by

So Timo, Have you considered the idea of storing all the email in a MySQL database? Seems to me that MySQL could somplify all the backend stuff that everyone struggles with and with replication one could create very massive and reliable systems. What would it take to use MySQL that way?

Good evening, I have not able able to run the http://ip-addr/src/configtest.php script, nor access Squirrelmail. Looking for suggestions on what I might have missed. When I try either http://ip-... or https://ip-..., I get the following reply Forbidden You don't have permission to access /webmail/src/configtest.php on this server. I got squirrelmail installed in /usr/share/squirrelmail and

Hi, You can rebuild the RPM on a CentOS 8 box from https://dl.fedoraproject.org/pub/epel/7/SRPMS/Packages/s/squirrelmail-1.4.23-1.el7.20190710.src.rpm or https://dl.fedoraproject.org/pub/fedora/linux/releases/31/Everything/source/tree/Packages/s/squirrelmail-1.4.23-2.fc31.20190710.src.rpm and install the resulting RPM.

Hello I use dovecot, postfix, mysql and squirrelmail as a mail server. it works well. Meanwhile I am novice at postfix. As you know, there is a change_password plugin on squirrelmail. I wish to add change_password plugin on squirrelmail. I couldn't find how to integrate postfix and change_password. How can I add it ?
