thanks for the pointer, i found the problem. if the new DEBUG_LOGIN_ENV variable is not present, one cannot connect to imap or pop3 (doesn't have anything to do with the toolchain update after all). after i added the variable, everything was right again (maybe i might suggest a less radical default behaviour). i looked up the function in authlib/debug.c: void auth_debug_login_init( void ) { const char *p=getenv(DEBUG_LOGIN_ENV);

auth_debug_login_level = atoi( p ? p:0 ); } and wondered if atoi does return zero here when p == NULL?

thanks again alex
