[Dovecot] lmtp bouncing -- Invalid parameters (in reply to MAIL FROM command)
I just configured postfix' virtual_transport to point at my dovecot director, but am seeing occational problems like this:
Aug 31 11:50:06 smtpgw postfix/lmtp[5339]: 69E2F5410D: to=<email@example.net>, relay=loadbalancers.example.net[192.168.42.17]:24, delay=0.15, delays=0.14/0.01/0/0, dsn=5.5.4, status=bounced (host loadbalancers.example.net[192.168.42.17] said: 501 5.5.4 Invalid parameters (in reply to MAIL FROM command))but can't find anything interesting in the dovecot logs.. Anybody have ideas for how to make postfix play nice with dovecot's lmtp ?
smtpgws% rpm -q postfix
postfix-2.3.3-2.1.el5_2
loadbalancers% rpm -q dovecot
dovecot-2.0.13-2
backendmailstorers% rpm -q dovecot
dovecot-2.0.13-2-jf

Further digging shows that these messages are from an address containing quotes and spaces:
mail from:<"a b"@no.no>
501 5.5.4 Invalid parametersTesting with postfix + dovecot lda (v1.2.16) the messages gets trough just fine. Is this auth_username_chars kicking in, or some other check of valid characters in lmtp from ?

This is fixed in v2.0.14.
Wow, you're quick :-) Thanks!
