About TLS variables
by Henry 04 Mar '21

04 Mar '21

Hello, I found the Variable %c only has TLS, Can it be using "TLSv1, TLSv1.1, TLSv1.2, TLSv1.3" instead of only TLS like as dovecot logging, this is really a most meaningful , thanks Variable %cLong name securedDescription “TLS” with established SSL/TLS connections, “TLS handshaking”, or “TLS [handshaking]: error text” if disconnecting due to TLS error. “secured” with localhost connections. Otherwise empty.

Re: Bug in renaming folder hierarchies - any reaction ?
by Klaus Steinberger 04 Mar '21

Hi, no comments on this? This is definitly with two different IMAP Clients reproducible. This led already to some message loss in user Mailboxes. > we discovered a major problem with renaming folders with subfolders > > testszenario: > > folders: > > test1 > test1/test1-1 > test1/test1-2 > > all 3 folders contain a test message > > after renaming the top level folder test1 to test2 following folders exist: > > test2 > test2/test1-1 > test2/test1-2 > > the subfolders test1-1 and test1-2 are empty, the top level folder contains the > correct message. > > > Now renmaing test2 back to test1: > > Alle folders again contain their messages. > > So this looks like during renaming the top level folder just the message > references for the subfolders got lost, and with renaming back they are there again. > > I can reproduce this behavior both with thunderbird and Horde Webmail as a > client, also it happens with a second different dovecot setup > Sincerly, Klaus Steinberger

Why Last-login?
by ＠lbutlr 04 Mar '21

04 Mar '21

I've noticed several threads over the last year or so about last-login, and I was curious WHY people care about tracking this in the database. I can see wanting to know if a user has logged in recently, but this seems quite easy to tell by simply looking at the time stamp and/or contents of the mail spool for the user. For example, on my system I can look at the timestamps on the 'new' folders in the user's maildir to see if they are getting mail, and if the folders are empty, I have a time stamp of when they last checked that mailbox, giving me a pretty accurate time for when they last logged in. For example, looking at one user: # ls -lsdtr /path/to/user/maildir/{new,.**/new} I can see that the most recent "new" mailboxes were accessed on 02 Mar 14:25 and 03 Mar 01:45, and I can see that the latter mailbox has files in it and the former mailbox does not (just by the size, without doing an extra ls of those directories), so I know that the last time the user logged in was about 14:25 or later yesterday and that they definitely have not logged in in the last 3h05, which seems close enough to me. Am I missing some reason I would need/want to keep track of that specific login time separately? -- 'But you ain't part of it, are you?' said Granny conversationally.

LDA File Permissions
by David Morsberger 03 Mar '21

03 Mar '21

All, I am looking for an easy way to setup LDA so that it creates files with group read permission. Currently LDA/Sieve create the '.dovecot.lda-dupes’ file with ‘0600’. My backup process needs to be able to read the file because it runs as a user that is in the same group as the LDA process. I looked into the source code and the file is opened with mode ‘0666’ as " fd = open(lock_info->lock_path, O_RDWR | O_EXCL | O_CREAT, 0666); This implies it is a umask issue. What is the best way to view and set the umask value for the LDA process on Ubuntu 20.04? Thanks, David

Can Dovecot honor Outlook's "leave mail on server for X days" setting?
by Steve Dondley 03 Mar '21

03 Mar '21

I googled around for a quite bit but surprisingly came up empty for an answer to this question which I'm sure has been broached before. I've got a linux box running dovecot/postfix using maildir format. I was surprised to learn that a client that had many GBs of email was running POP3, not IMAP. It turns out they had a setting to delete POP3 mail after X days turned on but it just went ignored. I know this is not how POP3 is supposed to work, but is there a way to get dovecot to honor the user's settings in Outlook? Or should I just tell the client to turn this off and use a proper IMAP account?
