Hi y’all,
Recently a mail got lost somewhere in our domino cluster, and I can’t seem to find out why or where. Here’s my situation:
A mail was sent from one domino user to another domino user, it landed in the sender’s “Sent” folder but never reached either the recipient’s or the CC’s inbox (or “All Documents” for that matter). The mail was sent through our webserver in our DMZ, who should route it to our main domino server in the internal network. In the Mail routing events log on both servers there is no entry of a mail at the time of sending. There is, however, a session between the webserver and the sender around that time (with Databases accessed: 3 Documents read: 0 Documents written: 0 Transactions: 9). Mails from the same user to the same recipient both 1 hour earlier and later worked perfectly.
Trying to troubleshoot this I came across a probably unrelated issue with mail tracking. I issued a tracking request both on internal and dmz servers to find the missing mail. On the internal server, the mail was just missing, as expected, but on the dmz server I had multiple general problems tracking mail:
-
when choosing Start at sender’s home server (which is the internal domino) I get “The remote server is not a known TCP/IP host”… which is impossible, as the server is constantly replicating with exactly that server. I triple checked all entries in connection documents, server documents, checked the server cache, but all the entries were correct. Same thing when I trace TCPIP connections: the server gets the DNS address returned, which cant resolve in the DMZ, but the appropriate IP is stored in the connection document and in the server cache. Why won’t the server use it?
-
when choosing Start at current server: “The full text index for this database is in use: dmz-domino-servername”. Which database is this? I tried to mess with mtstore.nsf (Domino MailTracker Store), but the error didn’t go away.
I’d appreciate any tips or suggestions you might have, mainly for the missing-mail-issue, as that’s a real showkiller.
