[Dovecot] Dovecot 0.99.9.1 and openssl-0.9.7a-5
by Robin Whittle 28 May '03

28 May '03

Hi Timo and others, Thanks for Dovecot! I just got it running under Red Hat 9.0 after spending many hours unsuccessfully trying to get Courier IMAP to run, although I have done it in the past. Here is a compilation glitch which may already be well known: I compiled dovecot-0.99.9.1 on my newly installed and recently updated (via Red Hat Network) system and the compilation stopped due to a missing file in the SSL headers: In file included from /usr/include/openssl/ssl.h:179, from ssl-proxy-openssl.c:14: /usr/include/openssl/kssl.h:72:18: krb5.h: No such file or directory In file included from /usr/include/openssl/ssl.h:179, from ssl-proxy-openssl.c:14: The currently installed OpenSSL RPM was openssl-0.9.7a-5. This lacks the file /usr/include/openssl/krb5.h . I understand that openssl-0.9.7b is OK, but I wasn't sure about whether installing this as a tarball from http://www.openssl.org would upset any other programs on this machine, or confuse the RHN update system. I didn't really need SSL and I couldn't see a specific option for disabling it, other than a general instruction about disabling modules with a ./configure option. So I tried ./configure --help and compiled it with: ./configure --without-ssl This worked fine. I really like the report at the end of the ./configure stage saying how the program will be compiled! - Robin // Robin Whittle http://www.firstpr.com.au // Melbourne, Australia http://fondlyandfirmly.com

[Dovecot] Dovecot in OpenBSD ports system
by Andrew Basterfield 27 May '03

27 May '03

Hi I have put together dovecot port for the OpenBSD ports system. The port has yet to be submitted, but is finished awaiting testing from a wider audience. I have been using dovecot successfully on OpenBSD/sparc64 -current for months now with no problems. Would you recommend including the CR+LF patch? http://cemetery.homeunix.org/OpenBSD/dovecot.tar.gz -- http://cemetery.homeunix.org

Ok: a little lame to answer my own question, but I created a CRUDE patch. It does NOT check why a connection failed, it just does a PQreset, and it SEEMS to work. Kind regards, Maikel Verheijen.

[Dovecot] still problem with load
by Farkas Levente 27 May '03

27 May '03

hi, we've got (and getting more) serious problem with load. I'm just calculate that ther is about 300 mailbox with 20Gb mails. and the whole system is _very_ slow and just getting slower and slower. it's a fast lan every client has 100Mb connection to the server with gigabit crad and gigabit switches. when I push the delete button in a mail I usualy have to wait 10,20 or 30 seconds (!!!) to deleted and show me the next one. dovecot eat so much io to the hard disk, that we can't do too much. currently at the same time about 100 clients are connected mostly with OE6. the server is a P4 server with 1GB ram and about 1TB hard disk. there is only one samba and dovecot on the server. and the load use to be something like this: ---------------------------------------- 10:47:38 up 3 days, 15:48, 2 users, load average: 4.64, 3.58, 3.43 230 processes: 225 sleeping, 5 running, 0 zombie, 0 stopped CPU states: 6.3% user 8.9% system 0.0% nice 0.0% iowait 84.6% idle Mem: 1022840k av, 1013588k used, 9252k free, 0k shrd, 80320k buff 826372k actv, 47324k in_d, 16904k in_c Swap: 4193608k av, 80612k used, 4112996k free 783088k cached ---------------------------------------- as you can see it use almost all ram (as the 2.4 kernmel used to do) but no cache. so the ram is enough. the more interesting part is the load while the idle usualy between 80-90% the whole system doesn't use any cpu (or just minimal). BUT at the same time the load is around 3,4,5 (!!!) which is too much, and more than acceptable. what's worse the reason is the io load on the hard disks. every process are waiting for io. in this case I usualy service dovecot stop killall imap <wait about one minutes> service dovecot start and the load goes back to 0.3-0.6. after an hour the same happend and I have to do the same.:-((( what's more in this case samba case that all (!!!) clients stops for a few seconds. since everybody use OE6 they always download all messages with huge mailboxes what's more dovecot index the whole system all the time. I assume this cause the load. IMHO 300 mailbox and 100 concurrent user is not such a big thing. is there any way to restrict dovecot not to use so much io? thanks in advance. -- Levente "Si vis pacem para bellum!"

[Dovecot] pop3 timeout when sending first message
by Mike Brown 27 May '03

27 May '03

I'm using FreeBSD 4.8 with dovecot from the ports collection. First I am first trying to fetch mail via POP3. Clients are both OE6 and Mozilla. Both exhibit the same behavior: the client says it is receiving message 1 of (however many), but nothing happens; no message data is transferred. Mozilla seems to keep waiting forever, but OE6 times out after 60 seconds and lets me stop waiting. I tried both with and without SSL. Authentication works fine in either case, but the mail xfer just doesn't work. There's nothing of interest in the logs. By the way, there seems to be no mention of what syslog facility is used by dovecot. What is it? I'm avoiding syslog for now and writing to specific files. In the info log I get this when the client logs in: pop3-login: May 25 23:10:44 Info: Login: mike [my.IP.addr.here] In the other log I get this when OE6 disconnects, following the timeout and prompting me to wait or stop: pop3-login: May 25 23:11:53 Warning: SSL_read() syscall failed: EOF [216.241.45.45] I'm not sure what else to do to try to debug this... Help? -Mike
