[Dovecot] Just setup Dovecot and having a small problem.
by Tom Ray 24 Apr '06

24 Apr '06

I've just installed Dovecot and am running into a bit of a problem with it. I'm using virtual email accounts and everything seems to be working up to a certain point. Let me break down how the server is setup. Each domain belongs under the directory /mail so it's path is basically: /mail/domain.tld. Within each domain directory there are two sub-directories etc and mail. Under /mail/domain.tld/etc I have two files setup aliases and passwd, the aliases file handles all mail aliasing for that domain and the passwd file holds the users account name and password. The password file has the accounts stored in the following format: user@domain.tld:(encrypted password):500:500:Virtual User:/mail/domain.tld/mail/user:/dev/null The password enctryption is basically htpasswd() style encryption. Now the problem I'm having is I keep getting authentication errors when I try to login via POP3 (I'm testing via command line so I do `telnet localhost 110`). At first I had only auth_debug_passwords=yes set and I was seeing this in the log file: Apr 23 18:54:19 www dovecot: auth(default): client in: AUTH^I1^IPLAIN^Iservice=POP3^Isecured^Ilip= 127.0.0.1^Irip=127.0.0.1^Iresp=AHRvbUBkZXRyb2l0b25saW5lLmNvbQBuZXdiZXJn Apr 23 18:54:19 www dovecot: auth(default): pam(user(a)domain.tld,127.0.0.1): pam_authenticate() failed: Authentication failure Apr 23 18:54:19 www dovecot: auth(default): passwd-file /mail/domain.tld/etc/passwd: Read 1 users Apr 23 18:54:19 www dovecot: auth(default): passwd-file(user(a)domain.tld, 127.0.0.1): unknown user Apr 23 18:54:20 www dovecot: auth(default): client out: FAIL^I1^Iuser= user(a)domain.tld So I can see it's reading the proper password file but it claims that user doesn't exist, however, that user does exist. When I turn on auth_verbose=yes and I'm still seeing the same errors in the log file. Can someone tell me what I'm missing here? I'm really on a time crunch with this, our mail server died friday morning and it's been put on me to fix it. They insist I use UW IMAP but I can't get it to work with the vitrtual users like the previous guy did. I've used Dovecot before but it's been two years and I can't remember how I got everything working before. They want things back to normal by Monday morning (tomorrow) so now I'm a bit stressed since I've lost most my weekend rebuilding the server and users. Any help would be appreciated. I thought I had this setup just right but I just can't get passed it telling me the user doesn't exsist.

[Dovecot] PINE + dovecot
by Richard Randriatoamanana 24 Apr '06

24 Apr '06

Hi list, I have installed dovecot on fedora4 and I migrated courier-imap to dovecot with instructions given on the site. everthing works fine for thunderbird, horde, evolution and mail/macosx.. but i have some pbs with pine because it doesnt read .subscriptions and directories aren't seen as it should be seen like in the .subscription. maybe i should reconfigure the .pinerc correctly, but what should I put in place then? does anyone have a .pinerc template that reads like other mail browsers with dovecot? Thanks in advance Cheers. Richard

When I have it set to disable_plaintext_auth = no I can get POP working but IMAP throws back errors. Any other thoughts?

[Dovecot] Solved problem with index corruption (new mail not seen)
by Tom Alsberg 24 Apr '06

24 Apr '06

Having had many problems in the past with IDLE not working, new messages not being seen from Thunderbird, and sometimes garbage seen as part of mailboxes, I eventually added some workaround/sanity check patch to the imap_sync_deinit code to reread the offsets from the index and that solved the problem. Now with beta7 (I've previously used beta2), this seems not to be necessary anymore. I installed vanilla beta7 and couldn't reproduce the problem in any way! I'm not sure what has changed there, and haven't yet checked if I see anything relevant, so this is just to let you know, and ask - any idea which change could have caused this. Happily I will soon be going on with working around other issues I have here, and start bugging you in the list again.

It's loading the proper password file, but it just doesn't see the user...it should be parsing it right correct?

[Dovecot] Bug: quota-maildir.c, array accessed out of bounds
by Bill Boebel 22 Apr '06

22 Apr '06

Timo, In src/plugins/quota/quota-maildir.c, in the maildirsize_read() function, if the maildirsize file is greater that 5120 bytes, this code breaks because the while loop executes multiple times, incrementing size to a value larger than 5120, and then size is later used to referece the buf array out of bounds. To fix it you could add a break statement after "size+= ret;" so that the while loop is always only executed once: char buf[5120+1]; ... size = 0; while ((ret = read(fd, buf, sizeof(buf)-1)) != 0) { if (ret < 0) { if (errno == ESTALE) break; mail_storage_set_critical(storage, "read(%s) failed: %m", path); } size += ret; } if (ret < 0 || size == sizeof(buf)-1) { /* error / recalculation needed. */ (void)close(fd); t_pop(); return ret < 0 ? -1 : 0; } /* file is smaller than 5120 bytes, which means we can use it */ root->total_bytes = root->total_count = 0; /* skip the last line if there's no LF at the end */ while (size > 0 && buf[size-1] != '\n') size--; buf[size] = '\0';
