Hi,
I try to compile dovecot -2.2.24 on Fedora 31 and get the following error:
iostream-openssl.c: In function ‘openssl_iostream_verify_client_cert’: iostream-openssl.c:118:37: error: dereferencing pointer to incomplete type ‘X509_STORE_CTX’ {aka ‘struct x509_store_ctx_st’} 118 | subject = X509_get_subject_name(ctx->current_cert); | ^~ make[3]: *** [Makefile:561: iostream-openssl.lo] Error 1
All openssl packages installed. What's the reason and how solve the problem?
Kind regards, Frank Elsner

Is there some reason you want to use ancient dovecot? You should use 2.2.36 at least.

Migration from 32bit to 64bit. I want to avoid problems, so I used the version I have compiled and used on the 32bit system.

I got dovecot-2.2.36.4 compiled but at start the log shows
dovecot[342614]: master: Dovecot v2.2.36.4 (baf9232c1) starting up for imap dovecot[342617]: ssl-params: Generating SSL parameters dovecot[342614]: master: Error: service(auth): command startup failed, throttling for 2 secs dovecot[342617]: auth: Fatal: master: service(auth): child 342623 killed with signal 11 (core dumped) dovecot[342614]: master: Error: service(auth): command startup failed, throttling for 4 secs
The configuration files are from dovecot-2.2.24 whre they worked perfect.
What to do to get it working? conf.d PS: I can provide dovecot.conf and conf.d/10-auth.conf if necessary.

I narrowed the probelem down to the warnings
Warning: service auth { client_limit=128 } is lower than required under max. load (768) Warning: service anvil { client_limit=256 } is lower than required under max. load (643)
Where comes max. load from?

These messages disappear after changes in the auth and anvil config but I ran into the following problem:

I guess the solution is simple but I can't find it :-(

Hi!
Can you try follow this guide to get a core dump
https://www.dovecot.org/bugreport-mail
then provide
gdb /usr/lib/dovecot/auth /path/to/core
bt full
on it. Would help narrowing down that bug.
Also doveconf -n could be useful.

Well, you need to get a core file first, which is documented in the page I linked.
Once you have a core file, somewhere, you should use
gdb /usr/lib/dovecot/auth /var/core/1234
and then try bt full.
There is no point using gdb without core file in this particular case.
If you are using systemd, you can do
systemctl edit dovecot
[Service]
LimitCORE=unlimited
