Sendmail problem - baffled
Our backup mail server (which I have just re-configured) tries to contact the primary mail server, and fails. My log shows repeatedly "connection refused": May 15 22:21:41 mx2 sm-mta-rx[8674]: q4FIhPij007483: makeconnection (mail.greenspot.fi.

dovecot replication - new and cur folders on mx1 and mx2
Hello, I have a question in regards to specific dovecot replication behaviour and I'm just wondering if this is actually an expected/normal behaviour, or just a version issue. I'm using dovecot 2.3.16 which is packed by default with latest Ubuntu 22.04.1 LTS server release. I setup dovecot replication pair (mx1 - mx2) which is working ok. MX1 has priority 10, MX2 has priority 20. I

dovecot replication - new and cur folders on mx1 and mx2
I can confirm this in a slightly different setting, but still using two-way sync between two dovecots. On e is 2.3.19.1 running on macOS Monterey, the other is 2.3.20 running in an alpine container on Ubuntu.

dovecot replication - new and cur folders on mx1 and mx2
It might have a noticeable effect on clients. I encountered (probably triggered by this in some way?) that I was unable to het the 'read' bit set in macOS Mail.app. Maybe (as I am doing HA with round robin) the Mail.app client got to one dovecot repository on one tcp connection and then on the other. Is there a reason why syncing tis move from new to cur is a bad idea? Gerben Wierda

problems with SSH-based clustering dovecot 2.1.1
Hello, I'm using dovecot 2.1.1 with vpopmail 5.4.30 with multiples domains and I have problems setting up synchronization in between multiple computers. All act like master (my clients can connect to any of the them and read their emails either via POP3 either via IMAP, inbound email gets on any of the machines). Each machine is on a different continent, there is no shared drive in between

Robust multivariate regression with rlm
Dear Group, I am having trouble with using rlm on multivariate data sets. When I call rlm I get Error in lm.wfit(x, y, w, method = "qr") : incompatible dimensions lm on the same data sets seem to work well (see code example). Am I doing something wrong? I have already browsed through the forums and google but could not find any related discussions. I use Windows XP and R

Load balancing email?
Currently, we have two mail relays for inbound messages, and a third for POP. The inbound messages go thru all the CPU-intensive anti-spam stuff, and then they relay it to the POP server for pickup. Currently, one of these is the "primary", and the other is "secondary", and I'd like them to be considered more or less as equals, since the "primary" system is

Configuring sendmail in a corporate environment
I have a stock CentOS 5 system as far as email (sendmail) is concerned that is on our corporate LAN. I am not trying to set up a mail server; I merely want our CentOS systems to be able to send out emails. This works as long as the recipient's domain is our local domain. Any email send to recipients that are not in our local domain get stuck in the queue: # mailq
