We are trying to get a murder configuration going. Thus far we have the backend, frontend, and mupdate (running on a frontend) servers mostly working.
Here are the outstanding issues to resolve - and all have to do with authentication. 1. Mailbox move from one backend to another using cyradm on a frontend fails with following errors: - couldn't authenticate to backend server: no mechanism available - Could not move mailbox: user.test100, Initial backend connect failed Note: we were having authenticaion problems with imap proxy till I hacked imapd.c as below: /* secprops = mysasl_secprops(SASL_SEC_NOPLAINTEXT); */ secprops = mysasl_secprops(0); There was a discussion thread with the above tip from Rob (Thanks Rob). However it made imap proxy work but not mailbox move from one backend to another. 2. sendmail fails to deliver messages via lmtpproxyd due to authentication problems.This is a typical mail deliver test that fails on the frontend server running lmtpproxyd. root@spnode21$ mail -v test100 Subject: test test .

Any help will be appreciated. Thanks. -- Gautam Das [EMAIL PROTECTED] Senior Systems Programmer Northeast Regional Data Center University of Florida
