hello, i get these lines in syslog when using post-login within imap-login: imap-login: Fatal: master: service(imap-login): child 574 killed with signal 11 (core dumps disabled) imap[5523]: segfault at 14 ip b7556276 sp bfc1c940 error 4 in libdovecot.so.0.0.0[b7529000+d4000] these are the relevant sections i added: service imap-login { executable = imap post-login } service post-login { executable = script-login /path/to/exec } i also used /bin/true as /path/to/exec to exclude the used exec itself as the reason. same result. version in use is 2.2.13-r1. this behaviour can be reproduced on two other of my gentoo-machines. described feature worked in previous version(s), don't know the exact version number. i'll cc this to mailinglist dovecot@dovecot.org thanks a lot for your suggestions. nico --- Portage 2.2.8-r2 (default/linux/x86/13.0, gcc-4.7.3, glibc-2.19-r1, 3.12.21-jason-bare-i686-1403781919 i686)
