So the OP can confirm this is the problem by manually running the libtool command but adding "-lssl", and if that works, then something screwed up Makefile or other build files.

[SUMMARY] trouble compiling Dovecot 2.2.31 on Solaris 10 SPARC - libssl_iostream_openssl.so is not portable!
by Jerry Kemp 26 Aug '17

26 Aug '17

I'm done. Good to go. Good compile + new binaries all built against the latest OpenSSL libraries. Big thank you to James, Joseph Tam and Aki Tuomi who game me pointers and kept me in the right direction. ........................................................................ These are the settings that made everything work for me. First, needed a current, up-to-date version of OpenSSL in place. Generally pretty easy task. I discovered that OpenSSL will not create shared libraries on Solaris using GNU make. No problem, everything worked just fine using the system /usr/ccs/bin/make . Back to Dovecot. Environmental variables - this is what I needed for my system. Although I'm a Sys V guy, never cared for the /opt thing, and ended up adopting /Applications from NeXT . setenv CPPFLAGS "-I/Applications/openssl-1.0.2l.32/include -I/Applications/openssl-1.0.2l.32/include/openssl" setenv LDFLAGS "-L/Applications/openssl-1.0.2l.32/lib" setenv SSL_CFLAGS "-I/Applications/openssl-1.0.2l.32/include -I/Applications/openssl-1.0.2l.32/include/openssl" setenv SSL_LIBS "-R/Applications/openssl-1.0.2l.32/lib -L/Applications/openssl-1.0.2l.32/lib" setenv LIBS "-lcrypto -lssl" setenv LD_LIBRARY_PATH "/Applications/openssl-1.0.2l.32/lib:/usr/lib:/usr/local/lib:/usr/xpg4/lib:/usr/openwin/lib:/usr/dt/lib" ........................................................................ Config statement: ./configure \ --prefix=/Applications/dovecot-2.2.32.32 \ --with-ssl=openssl \ --with-ssldir=/Applications/dovecot-2.2.32.31/certs ........................................................................ From there, it was run "make" then wait for the compile to finish. It had been a while since I did a fresh Dovecot compile, and in the past, I had just used the system provided OpenSSL install. This took a bit more work. Hope this can help out someone else in the future. Thank you, Jerry

dovecot: config: Error: BUG: Config client connection sent too much data
by Tony 26 Aug '17

26 Aug '17

Hello, Today I started noticing a very odd Dovecot error in the mail logs across 2 replicated Dovecot hosts via dsync. I have searched the Dovecot archives, Google, back tracked, downgraded Dovecot to earlier versions from earlier this year and ruled everything out I could think of to no avail. There really are not any helpful reports with what I am specifically seeing. The strange thing is only vmail(a)domain.net is repeatedly shown in the log. The error looks like this. *Aug 24 22:46:02 orbitron dovecot: config: Error: BUG: Config client connection sent too much data****Aug 24 22:46:02 orbitron dovecot: doveadm(vmail@domain.net@domain.net@domain.net@domain.net@domain.net@domain.net@domain.net@domain.net@domain.net): Fatal: Error reading configuration: read(/var/run/dovecot/config) failed: read(size=8192) failed: Connection reset by peer*** $ dovecot --version 2.2.31 (65cde28) Dovecot #1: Linux kernel 4.9.36-x86_64 Dovecot #2: Linux kernel 4.12.8-x86_64 Here are the latest Dovecot updates performed this year. [2017-04-29 14:45] [ALPM] upgraded dovecot (2.2.28-2 -> 2.2.28-3) [2017-05-02 23:05] [ALPM] upgraded dovecot (2.2.28-3 -> 2.2.29.1-1) [2017-06-11 17:20] [ALPM] upgraded dovecot (2.2.29.1-1 -> 2.2.30.2-1) [2017-06-30 22:46] [ALPM] upgraded dovecot (2.2.30.2-1 -> 2.2.31-1) When Dovecot was last updated back on June 30, I did `systemctl daemon-reload` but never actually restarted the Dovecot daemon until what seems like today. The only thing I did today was edit /etc/dovecot/conf.d/10-auth.conf by simply enabling "*auth_username_format = %Lu*" which was commented out before I enabled it. That is the /*only*/ thing that I tested. After I was done testing I went back and commented out the same thing so it reads "*#auth_username_format = %Lu*" and of course restarted Dovecot. I really doubt this has anything to do with what I am reporting as auth is not the problem in this case. Thank You, Tony

I would also check where the "... is not portable!" messaage is generated. If it's done by the configure script, you can look at the test to give you a hint as to why this message was generated. For my setup, I did much the same as you but didn't have to set the SSL_CFLAGS, SSL_LIBS environment variables, nor did I set the --with-ssldir configure option (although your setup may need it). Maybe check output of file /Applications/openssl-1.0.2l.32/lib/libssl.so.1.0.0 just to make sure your library's arhitecture matches your expectation. > # ./configure \ > --prefix=/Applications/dovecot-2.2.31.32 \ > --with-ssl=openssl \ > --with-ssldir=/Applications/dovecot-2.2.31.32/certs \ > --with-storages=mbox,maildir,imapc,pop3c I believe "--with-storages" option is now obsolete: all the storage backends are built, whether you ask for it or not.

trouble compiling Dovecot 2.2.31 on Solaris 10 SPARC - libssl_iostream_openssl.so is not portable!
by Jerry Kemp 26 Aug '17

26 Aug '17

attempting to compile dovecot 2.2.31 on Sun/Oracle Solaris 10 SPARC. configure goes fine. First sign of problems during compile is with this warning: ............................................... *** libssl_iostream_openssl.so is not portable! ............................................... actual ERRORS - Soon, compile errors out with undefined symbols. Output at bottom of note. ............................................... additional system information. OpenSSL - just prior to dovecot compile attempt, I downloaded and successfully compiled OpenSSL version 1.0.2l (to include a successful "make test" ) in directory /Applications/openssl-1.0.2l.32 , want to link against current code and not mess with system provided SSL stuff in /usr/sfw/* ENV setting and configure command line prior to compile - # setenv CPPFLAGS "-I/Applications/openssl-1.0.2l.32/include -I/Applications/openssl-1.0.2l.32/include/openssl" # setenv LDFLAGS "-L/Applications/openssl-1.0.2l.32/lib" # setenv SSL_CFLAGS "-I/Applications/openssl-1.0.2l.32/include -I/Applications/openssl-1.0.2l.32/include/openssl" # setenv SSL_LIBS "-R/Applications/openssl-1.0.2l.32/lib -L/Applications/openssl-1.0.2l.32/lib" # ./configure \ --prefix=/Applications/dovecot-2.2.31.32 \ --with-ssl=openssl \ --with-ssldir=/Applications/dovecot-2.2.31.32/certs \ --with-storages=mbox,maildir,imapc,pop3c ................................................. What is the .32 stuff I see appended to directories? I did a 32 bit compile of the latest OpenSSL, then , the data shown here is also for a 32 bit dovecot build to link against the 32 bit OpenSSL build. I have been fighting this for a few days, and had also done an identical 64 bit OpenSSL, then dovecot build. The 64 bit dovecot build failed in the same way and place. Additionally, when I did the 64 bit compile, I ended up pulling down a current copy of ZLIB, and doing a 64 bit compile of that library also, and installing it under /Applications then linking against that. the system ZLIB library is/was 32 bit, and if there is a 64 bit version provided by Sun/Oracle, neither myself or the "configure" script could locate it. Not a big detail, ZLIB is an easy compile, just trying to share all relevant data. ................................................. Try again with the latest code. I have been working/fighting 2.2.31 for a couple of days. I see earlier today, dovecot 2.2.32 was released earlier today, so before anyone runs to put on their "*L*" cap and advise me to pull down the latest code, I already did that, and the compile errors out in the same place. ................................................. If your still reading, thank you, just want to provide as many relevant details as possible. Again, symbol errors from compile are at bottom. TIA for any helpful comments or suggestions, Jerry ...............................................................

Hi @all, after re-installing one of my two frontends/proxy-servers I get the following error messages after some time (sometimes after 1h, sometimes after 24h): 11:23:55 imap-login: Error: socketpair() failed: Too many open files 11:23:55 imap-login: Error: socketpair() failed: Too many open files 11:23:56 imap-login: Error: socketpair() failed: Too many open files 11:23:56 imap-login: Error: socketpair() failed: Too many open files 11:23:57 imap-login: Error: socketpair() failed: Too many open files 11:26:17 imap-login: Error: socket() failed: Too many open files 11:26:17 imap-login: Error: proxy(post(a)example.com): connect(172.17.1.1, 143) failed: Too many open files (after 0 secs): user=<post(a)example.com>, method=PLAIN, rip=x.x.x.x, lip=x.x.x.x, TLS, session=<FgPWTWhXa8dQjLoi> 11:26:17 imap-login: Error: socketpair() failed: Too many open files 11:26:17 imap-login: Error: proxy: SSL handshake failed to 172.17.1.1:143: user=<post(a)example.com>, method=PLAIN, rip=x.x.x.x, lip=x.x.x.x, TLS, session=<HALWTWhXasdQjLoi> 11:26:17 imap-login: Error: socket() failed: Too many open files 11:26:17 imap-login: Error: proxy(post(a)example.com): connect(172.17.1.1, 143) failed: Too many open files (after 0 secs): user=<post(a)example.com>, method=LOGIN, rip=x.x.x.x, lip=x.x.x.x, TLS, session=<HALWTWhXasdQjLoi> 11:26:17 imap-login: Error: socketpair() failed: Too many open files 11:26:17 imap-login: Error: proxy: SSL handshake failed to 172.17.1.1:143: user=<post(a)example.com>, method=LOGIN, rip=x.x.x.x, lip=x.x.x.x, TLS, session=<FgPWTWhXa8dQjLoi> 11:26:17 imap-login: Error: socket() failed: Too many open files As I switched from KVM to LXC my first idea was that this could be caused by LXC but this even happens with KVM. I tried dovecot 2.2.31 and 2.2.32.rc2. OS is Debian 9. These problems don't occur on my old machine (Debian 7). Any ideas?
