so it will listen on the same socket.

the effect with sendmail is as below

Mar 23 21:23:29 <2.3> puchar dovecot: auth: Error: Authentication client not compatible with this server (mixed old and new binaries?)

do i need to specify something while compiling sendmail to make it compatible?

solved by setting saslauthd to authenticate over imap - through dovecot server. testsaslauthd shows it works fine.

The optimum setup though would be to auth directly against dovecot. A redirection through saslauthd seems unnecessary.

but it seems sendmail strips domain name from entered login.

What backend do you use for authentication ? (system / virtual users ?)

Yassine.

No, it is saslauthd. Check the documention and see the "-r" parameter of saslauthd.

found it a minute before reading this e-mail. thank you

works fine. almost ;)

Why authenticating over imap takes so slow?

my saslauthd runs like that

/usr/local/sbin/saslauthd -a rimap -O 127.0.0.1 -n 0 -r

imap server is handled by dovecot of course.

to be sure it's not sendmail i've tried testsaslauthd

testsaslauthd -u wojtek@puchar.net -p mypassword

works but takes 5-10 seconds. server is lightly loaded.

telnet 127.0.0.1 imap responds instantly.

what to check?

login_trusted_networks = 127.0.0.1

fixed the speed problem
