similar to: DoS (was IMAP-auth on LAN and otherwise)

Hello, Thunderbird has been bugging us with connection errors. Dovecot is installed on a local server that carries a local IP and a public IP. When Thunderbird on a local client connects successfully, Wireshark shows a SYN request from the client's IP on LAN to the public IP of the server, followed by the ACK from the same public IP. When Thunderbird on the same local client fails to connect,

I'm not sure that this is a dovecot issue. For me it sounds more that the router somehow learned dovecots LAN ip and then takes a shortcut by sending the packets directly to dovecot on routers LAN interface instead of going all the way to the WAN interface and then back to LAN. You could verify if that is the case by tcpdump on dovecot and see on what interface the request comes is. If that

Cyrus IMAPd provides exactly that, easily ;-) https://www.cyrusimap.org/imap/download/installation/manage-dav.html Alexander

I still find impediments to the adoption of any of those "solutions". Too many software dependencies, like PHP, DB, python, and a virtual machine. --- There are two portable file formats for calendar and contacts that work across applications and systems, but no server that can use them, and use them safely.

I would rather choose what to install.

By default, Apple Mail downloads all e-mails from server's account. Previous versions of this client allowed to opt-out. The latest two versions? however, only allow to opt-out from downloading the attachments. The stress on the server is unbearable. We cannot ask users to be considerate: this is the default behaviour of Apple Mail. We need a server-side solution to the problem. Please

> Password schemes: HMAC-MD5, RPA, SKEY, PLAIN-MD4, LANMAN, NTLM, SMD5 The web is flooded with plain text passwords and hashed passwords harvested from hacked servers. Dovecot stores passwords with the same scheme used for client authentication. Therefore, we use crammd5/hmac-md5. It does not look like much, but is better than plaintext. As md5 is about to go, and I have no intention to

Sorry for top posting, my client is still broken. I have never seen the ghost of a "system-alerts" or similar "well-known" mail folder in the past 30 years. Compliance with an RFC obscure feature is compellong us all to clear subscriptions fol ders by hand. As we meet the problem over and over again, a non-RFC configuration option could solve the problem, and it would be

Hello! Please share your favourite open-source Notes app for Android, as I am struggling to find one compatible with IMAP.

I meant to disable it when configuring the source, and thus when running make check. The test fails on 2.3.0 only, the 2.2 branch did not have this problem.
