2.3 -> 2.4 segmentation fault
Hello there,
First, thanks for the terrific job you're doing. Dovecot rocks!
I installed some time ago Dovecot on my macbook with Homebrew, that was Dovecot v2.3.18. I recently upgraded everything I installed with Homebrew to the latest which brought Dovecot to v2.4.0. I then modified my dovecot.conf file to make it work with this latest version but now, I constantly get a segmentation fault when I use any /dove/ command : zsh: segmentation fault doveadm
Also, while it looks like Dovecot is listening at the specified port, my email client cannot connect anymore complaining the server refused the connection. tcp4 0 0 127.0.0.1.10143 *.* LISTEN 662

Hello Aki,
Thanks for the suggestion. With this being set: "default_vsz_limit = unlimited", I don't get the seg fault with doveadm anymore.
However, I now have :

Hello Aki,
2.4.0 is the latest available via homebrew. I'm not too sure I can upgrade manually.

This is of course the same issue I’ve been raising for weeks now. I’ve been waiting for the home brew upgrade.

John, this is not down to dovecot, it's more homebrew related. I don't feel I can do it myself so I'm left with the homebrew team (@carlocab ;) ) to do it when they have time, so as you I suppose. Once I can upgrade, I'll let this list know whether it fixes my problem.

Hello there, John,
I don't know which of the 2 actions below I took helped but the result is I got dovecot 2.4.0 working at the end.
I originally installed Homebrew on an Intel based MacBook and I'm now on Apple M2. Hence, I was running running brew with Rosetta. I decided to re-install brew for M2 following https://github.com/orgs/Homebrew/discussions/417#discussioncomment-2556937
Before trying to upgrade dovecot, it used to listen at port 10143. I realised late after the upgrade dovecot listens at port 143 (doveconf -a => imapc_port = 143) and therefore changed my client IMAP account settings.
Hope this helps.
