Hi everybody, I've got an Unitek iZi UPS 525 with a serial interface. The supplied cable looks fairly simple: RX->RX , TX->TX and GND->GND. Using this cable and Minicom with 2400 8N1 I'm able to issue commands to the UPS using the "Megatec Protocol" http://www.networkupstools.org/protocols/megatec.html so I know the UPS is fairly "intelligent" :-) and the

Happy holidays! I am experiencing an issue when trying to check my mail using IMAP. with Dovecot I have tried checking my mail using a full GUI client (Thunderbird) and telnet. Both times I get disconnected before all of my messages can be downloaded and I see an error in my mail log. Here are the details: [root at cust19-1-prod-domain userqa]# dovecot --version 2.0.9 [root at

I'm resurrecting this again because I'm getting pretty close to possibly being ready to install a brand new dovecot server (finally), but I still need for dovecots LMTP to add the x-original-to header. So... was this completed quietly, or is support for it still not there? Thanks, Charles On Tue Apr 28 2015 15:27:07 GMT-0400 (Eastern Standard Time), Charles Marcus <CMarcus at

While the rest of you were chatting about the smallest * server, I was sitting her staring at the telephone hanging on the wall. It is a Western Electric set in a varnished pine box with an earpiece you hold in your left hand and a mouthpiece attached to the box. You crank the magneto with your right hand to signal the switchboard. The two dry cells inside are dated 1935, and I'm

I set up a shared mailbox with dovecot and it basically works. However, before I can imap SELECT or STATUS the shared mailbox I have to first do an imap LIST, i.e, . list "" * If list is not done first, the imap select or status command on the shared mailbox results in a "NO" response with "mailbox doesn't exist" response text. I can provide more

I have a few IP addresses attached to an interface without problems. I also have some chrooted environments attached to these IP addresses. Is there a way to make connections (telnet) from these environments look like they are coming from the aliased IP''s rather than the main IP address? Thanks for any help Kevin.

Is there a way to get dovecot to send automatic flag updates? I notice that when I have two clients connected and one of them reads a new message, the server sends a status update which contains the number of unseen messages, but doesn't specifically say which ones have changed.
