Astib <as...@mag0.net> changed: What |Removed |Added ---------------------------------------------------------------------------- CC| |as...@mag0.net --- Comment #1 from Astib <as...@mag0.net> --- Even a bit weird as this report is quite old, this may match my observation to with my Kmail: Running Kubuntu 24.04: ``` kmail/noble-updates,now 4:23.08.5-0ubuntu5.1 amd64 [installed] full featured graphical email client kmailtransport-akonadi/noble,now 23.08.5-0ubuntu3 amd64 [installed,automatic] mail transport akonadi library ``` I found something - because I have TLS mitm proxy at disposal, I discovered that there is problem in PLAIN base64 calculation when composing the AUTH PLAIN payload. It should be: `<account_name>:<password> ` Problem is not related only to IMAP, but it's the case also for SMTP. What it does (IMAP - separator is not ':'): `<account_name><account_name><password>` What it does (SMTP - separator is missing) `<account_name><password>` If I replace AUTH PLAIN payloads with correctly composed ones, all works well. Since I replaced payload inline with mitm proxy, I guarantee it's not a password issue, or some user or server error/mistake. The problem is probably in the code which composes username and password into base64 payload. It _may_ be depending on CAPABILITIES sent from server, because my other IMAP/SMTP services work well. -- You are receiving this mail because: You are watching all bug changes.
