Checking for incoming emails on the serverThere are several reasons why an email message that is supposed to have arrived may not be in the user's mailbox. - The message has been blocked by an antispam before arriving on the BlueMind server. In that case, you must check your antispam solution's logs
The message is stuck in the BlueMind server's postfix queue. This typically happens when a user's usage quota is at full capacity. The email will be held in the postfix queue for 3 days. If after 3 days the server hasn't been able to deliver it, a non-delivery message will be sent to the sender. You can check whether the message is in the postfix queue using the command: | Bloc de code |
|---|
[root@bluemind ~]# postqueue -p
-Queue ID- --Size-- ----Arrival Time---- -Sender/Recipient-------
4E4D83AF8E 943 Thu Mar 2 07:10:58 full@bluemind.net
(host 192.168.124.72[192.168.124.72] said: 452 4.2.2 Over quota SESSIONID=<cyrus-4311-1488438658-1> (in reply to RCPT TO command))
full@bluemind.net |
To release the message, you can either ask the user to delete some emails or increase their quota, then wait for the message to be delivered or force postfix to try to deliver messages again using the postqueue command -f
If the email message is not stuck, you can find tracks of its arrival in the postfix logs (/var/log/maillog ou /var/log/mail.log): | Bloc de code |

In this case, you can see that user2@domain.net is the sender of message AM5PR04MB3219A293B59D96973D338B01D2290 and it has been delivered to this user. The message-id is the identifier for the message only and it is found in the email header. The number at the end of the lmtp line (2294 in this case) corresponds to the email id in the user's INBOX folder, you can therefore find it in /var/spool/cyrus/data/b/bluemind_net/b/bluemind.net/u/user/user/2294. Following email movements/deletionsThe operations performed on an email message can be tracked through the bm-ips IMAP proxy logs: /var/log/bm-ips/ips.log Email movementsYou can find this information by searching the user's log in ID or the email ID | Bloc de code |
