Hello, I'm using dovecot & postfix to bring smtp auth to our customers. Normal mail clients have no problem at all and I'm so satisfied. However, we're having problems with Microsoft Exchange server clients. We're using our postfix-dovecot server as smarhost for several Exchange Servers, and we wish to use TLS + basic authentication for these outgoing mails. But it seems that

Hi, Since upgrading our mail servers to Postfix/Dovecot, we've seen a rather large increase in botnet brute force password attacks. I guess our old servers were too slow to suit their needs. Now, when they hit upon a valid user, it's easy to see what passwords they are trying (we've enabled auth_debug_passwords and set auth_verbose_passwords = plain). We can easily have log

hi (especially to you, Aki), so to solve the previous UID issue, i went the full LMTP route. however, i seem to be having problems with the prefetch userdb (i'm trying to minimize load on the LDAP server). namely, the log says: Aug? 2 00:15:35 rhyno postfix/submission/smtpd[21158]: 5EEF35C05C5: client=localhost[127.0.0.1], sasl_method=login, sasl_username=aik Aug? 2 00:15:40 rhyno

Hi, I have some problem in Dovecot authorization in Exim for outgoing SMTP. Version of Exim is 4.69 and the Exim was compiled with "AUTH_DOVECOT=yes" and "AUTH_PLAINTEXT=yes". Version of Dovecot is 1.2.12. I use SSL for IMAP. Is Exim neccesary to use SSL(TLS) for authorization of outgoing SMTP? Configuration files is as follows; - Exim

Hello! After moving from Centos 5.6 to Centos 6, I figured that Sendmail minor version was updated from 8.13.x to 8.14 and Dovecto from 1.2 to 2.0.x In previous configuration SMTP auth worked fine (no SASAUTHD neccessary) for virtual users table. Dovecot was authenticating virtual users virtual checking dovecot.passwd file. I'm not sure how Sendmail was processing SMTP AUTH for virtual users

One of my accounts was having login failures when trying to send mail, but was able to check mail. I tried everything I could think of to see what the issue might be, but eventually went in and reset the password in the sql database (I knew the password, so I reset it to the same password). {SHA256-CRYPT}$5$VuS? {SHA256-CRYPT}$5$VI7? So the password was updated properly. Clients can still

you mean i should define another, "fallback" userdb service if prefetch doesn't work for some reason? is it the problem that it's a chicken and egg scenario and with LMTP address verification (from postfix) there is no login beforehand so then dovecot needs to consult the userdb once again and having no fallback mechanism, it gives up? i can understand that, but then it

ah well, but i'm not using sql at all. here's doveconf -n: # 2.2.27 (c0f36b0): /etc/dovecot/dovecot.conf # Pigeonhole version 0.4.16 (fed8554) # OS: Linux 4.9.0-4-amd64 x86_64 Debian 9.4 auth_cache_negative_ttl = 0 auth_mechanisms = plain login hostname = rhyno.tech mail_debug = yes mail_location = maildir:~/mail namespace inbox { ? inbox = yes ? location = ? mailbox Drafts { ???

as far as i understand postfix has no way to know the username of such failed logins like below, IMHO dovecot internally does because it verifies against the sql-userdatabase is there a way that dovecot logs the username? after ask the users to change their passwords for safety caused by Heartbleed it was easy to write a tool find forgotten devices in case of IMAP/POP3 but especially Apple
