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? lmtp_address_translate lmtp_hdr_delivery_address = final lmtp_proxy = no lmtp_rcpt_check_quota = no lmtp_save_to_detail_mailbox = no lmtp_user_concurrency_limit = 0
Eg. When I send email from gmail it looks like this (reason: 553 5.1.2 <xxxx at 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'.
