[Dovecot] dovecot does not find libpam when compiling with customized prefix
Hello everybody, I try to compile dovecot 2.1.7 with a customized --prefix setting and --with-pam . Although I installed libpam into the same --prefix, dovecot does not find it: checking for pam_start in -lpam... no configure: error: Can't build with PAM support: libpam not found The same or a similar problem seems to have appeared 4 years ago: http://www.dovecot.org/list/dovecot/2008-February/028750.html Which libpam file does dovecot expect in which directory? And possibly there is something wrong with the pam_start function? Thanks in advance, Roland

Re: [Dovecot] Dovecot antispam plugin bug: got an empty message
It looks that I have misconfigured the dovecot plugin:
plugin {
antispam_dspam_binary = /usr/bin/dspam # should be dspam
# antispam_dspam_binary = /usr/bin/dspamc # does not work
antispam_signature = X-DSPAM-Signature
antispam_signature_missing = move
antispam_spam_pattern_ignorecase = Junk;Junk.*
antispam_trash_pattern_ignorecase = Trash;Deleted Items
antispam_backend = dspam
antispam_dspam_args = --user;%u;--deliver=;--source=error;--
signature=%%s
antispam_dspam_spam = --class=spam
antispam_dspam_notspam = --class=innocent
}

clause

It seemed I had to add something like that in dovecot-sql.conf
iterate_query = select MBOX_NAME AS username from M_MAILBOX WHERE MBOX_NAME =
'%n';
so I did but I'm still getting no usernames
so I enabled general_log in mysql
that what I get:
select MBOX_NAME AS username from M_MAILBOX WHERE MBOX_NAME = ''
It seems like direcotor don't expand variables, I've tried both - %n and %u -
nothing
any help ?
