Eg. When I send email from gmail it looks like this (reason: 553 5.1.2 xxxx@gmail.com... Unrecognized host name gmail.com.)
-----Original Message----- To: dovecot Subject: sendmail -> lmtp 501 5.6.0 Data format error
When changing in a working setup sendmail.mc
From this MAILER(smtp)dnl MAILER(procmail)dnl
To this
FEATURE(local_lmtp',[IPC]',`FILE /var/run/dovecot/lmtp')dnl
MAILER(local)dnl
I am getting these errors '501 5.6.0 Data format error' and ' Unrecognized host name'.
What should I change in my lmtp config? Could this be related that messages are being relayed from other servers?
