[Dovecot] mailserver pop3-login: Disconnected
by Shawn Bishop 13 Dec '05

13 Dec '05

Good Day I am having the following serious problem. I am running CentOS 4.1 with dovecot 0.99.11. The users are using POP3 login to retrieve mail. For the last 2 days we have experienced the following problems. I have recreated all the users and reconfigured the dovecot,but the same problems occur. Please see attached /var/log/maillog messages It appears so users login whereas others cant.Eventually after about an hour none of the users can login.

[Dovecot] Case sensitive nightmare
by Erik Petersen 12 Dec '05

12 Dec '05

It took me 4 days to figure this out and I sure hope someone can help me solve it. My Setup: Postfix + MySQL + dovecot dovecot.conf: default_mail_env = maildir:/var/spool/vmail/%d/%n/Maildir password_query = SELECT password FROM mailbox WHERE username='%u' user_query = SELECT maildir, 108 AS uid, 108 AS gid FROM mailbox WHERE username='%u' The virtual host schema is postfix.admin compatible but I¹m not using it (phpMyAdmin is actually easier to use). When foo(a)domain.tld, abrand new account, logs in using an IMAP client (any client; squirrelmail, OE, tbird, Apple...) a maildir is created named domain.tld/foo/Maildir¹ and everything is good. Now I login as Foo(a)domain.tld and then as fOo(a)domain.tld and then as foO(a)domain.tld then so on for every case variation. Each of these accounts can login correctly, they are seen as being the same account by dovecot. On the other hand they are not seen as being the same mailbox! When I check my mail spool I see one maildir for every case variation (domain.tld/foo/Maildir, domain.tld/FOO/Maildir, etc.) It would seem to me that the queries above would fail for the different variations of the name but they don¹t seem to. Is dovecot converting %u to lower case for the query on the virtual users table but then using it unconverted when looking up the Mairdir for the account? If the username column has the value foo(a)domain.tld1 how does SELECT * FROM table WHERE username=¹FOO(a)domain.tld1 match the row? Also puzzling is that I select a column named maildir which has the path to the mailbox in it (using the correct case). Even if SELECT pigs fly¹ AS when WHERE FoO¹=¹foo¹ the maildir path for the account is being returned which is domain.tld/foo/Maildir¹ so how does domain.tld/FoO/Maildir¹ get created? This is both a pain in the nuts support nightmare but also a security problem (albeit fairly limited). An account named ³barneyrubble² could generate a significant number of maildir directories if you logged in with every variation thereof. Any assistance would be greatly appreciated. Thanks

[Dovecot] configuring squirrelmail with tls for both imap & smtp on FC3 with dovecot & postfix
by ankush grover 12 Dec '05

12 Dec '05

hey friends, I am trying to secure my mail server.I have enabled TLS support in postfix(version postfix-2.1.5), now I am trying to configure squirrelmail(version 1.4.4-1 rpm) for tls/ssl support.In config.php i have choosen use_imap_tls=true and use_smpt_tls=true. Moreover If I send any mail from squirrelmail there are no entries for ssl or tls in maillogs whereas If I send the mail through evolution I can see tls/ssl entries in maillogs. starting TLS engine Dec 12 12:30:08 cluster1 postfix/smtpd[7965]: setting up TLS connection from [192.168.1.68] Dec 12 12:30:08 cluster1 postfix/smtpd[7965]: SSL_accept:before/accept initialization Dec 12 12:30:08 cluster1 postfix/smtpd[7965]: SSL_accept:error in SSLv2/v3 read client hello A Dec 12 12:30:08 cluster1 postfix/smtpd[7965]: SSL_accept:error in SSLv2/v3 read client hello B Dec 12 12:30:08 cluster1 postfix/smtpd[7965]: SSL_accept:SSLv3 read client hello A Dec 12 12:30:08 cluster1 postfix/smtpd[7965]: SSL_accept:SSLv3 write server hello A Dec 12 12:30:08 cluster1 postfix/smtpd[7965]: SSL_accept:SSLv3 write certificate A Dec 12 12:30:08 cluster1 postfix/smtpd[7965]: SSL_accept:SSLv3 write server done A Dec 12 12:30:08 cluster1 postfix/smtpd[7965]: SSL_accept:SSLv3 flush data Dec 12 12:30:08 cluster1 postfix/smtpd[7965]: SSL_accept:error in SSLv3 read client certificate A Dec 12 12:30:08 cluster1 last message repeated 2 times Dec 12 12:30:08 cluster1 postfix/smtpd[7965]: SSL_accept:SSLv3 read client key exchange A Dec 12 12:30:08 cluster1 postfix/smtpd[7965]: SSL_accept:error in SSLv3 read certificate verify A Dec 12 12:30:08 cluster1 last message repeated 3 times Dec 12 12:30:08 cluster1 postfix/smtpd[7965]: SSL_accept:SSLv3 read finished A Dec 12 12:30:08 cluster1 postfix/smtpd[7965]: SSL_accept:SSLv3 write change cipher spec A Dec 12 12:30:08 cluster1 postfix/smtpd[7965]: SSL_accept:SSLv3 write finished A Dec 12 12:30:08 cluster1 postfix/smtpd[7965]: SSL_accept:SSLv3 flush data Dec 12 12:30:08 cluster1 postfix/smtpd[7965]: TLS connection established from [192.168.1.68]: SSLv3 with cipher RC4-MD5 (128/128 bits) But when I did the config.test for squirrelmail I got the below error Checking IMAP service....
