Strange thing, I can't send emails when I do in dovecot.conf file (which is
default settings):
auth_mechanisms = plain login
passdb {
args = /etc/dovecot/dovecot-sql.conf
driver = sql
# driver = passwd-file
# args = scheme=cram-md5 /etc/dovecot/cram-md5.pwd
}
I can send emails when I set in dovecot.conf file:
auth_mechanisms = plain login cram-md5
passdb {
#args = /etc/dovecot/dovecot-sql.conf
#driver = sql
driver = passwd-file
args = scheme=cram-md5 /etc/dovecot/cram-md5.pwd
}
Besides in dovecot.conf file I added:
auth_debug=yes
auth_verbose=yes
I attach file with dovecot -a output.
