Hi, I have a relay server where different application servers send emails to it. An application server is sending email with the size around 17 MB but the relay server is not accepting it citing the below warning:
++++++ Jun 18 09:47:05 smtp1 postfix/smtpd[43832]: 66F259E10043: client=<server name>[xxx.xxx.xxx.xxx] Jun 18 09:47:07 smtp1 postfix/cleanup[46274]: 66F259E10043: message-id=<messageid@domain> Jun 18 09:47:09 smtp1 postfix/smtpd[43832]: warning: 66F259E10043: queue file size limit exceeded ++++++ The application server logs contains: 552 5.3.4 Error: message file too big Please check the below postconf of relay server for the sizes: # postconf | grep size berkeley_db_create_buffer_size = 16777216 berkeley_db_read_buffer_size = 131072 body_checks_size_limit = 51200 bounce_size_limit = 50000 header_size_limit = 102400 lmdb_map_size = 16777216 mailbox_size_limit = 51200000 message_size_limit = 48916070 tcp_windowsize = 0 I am sure it is not message_size_limit because when tested it is giving clear error message like "NOQUEUE: reject: MAIL from [xxx.xxx.xxx.xxx]: 552 5.3.4 Message size exceeds fixed limit" I am confused what this error "queue file size limit exceeded" means? Kindly help. Thank you.
