saslauthd在段落运行一段时间后运行

我使用postfix和courier和mysql进行身份validation。

最近我有一些分段错误，导致sasl deamon崩溃。 看来，这与我的邮件服务器上的字典攻击有关。 在日志文件中，我得到了saslauthd的段错误

segfault at 0 ip 00007fe3107a3d8e sp 00007ffc2b007de8 error 4 in libc-2.19.so 

• libsasl2-2版本： 2.1.26.dfsg1-13+deb8u1
• 后缀版本： 2.11.3-1

saslauthd conf：

 START=yes DESC="SASL Authentication Daemon" NAME="saslauthd" MECHANISMS="pam" MECH_OPTIONS="" THREADS=5 OPTIONS="-c -m /var/spool/postfix/var/run/saslauthd -r" 

后缀main.cf

• Postfix发送垃圾邮件
• Postfix将日志logging到远程日志主机
• 只有一个地址的ISPConfig / postfix邮件转发失败
• 无法用自己的后缀发送Hotmail邮件
• 有没有办法configuration后缀绕过垃圾邮件/ RBL检查特定的目标主机名或用户名？

任何build议，以阻止saslauthd崩溃？

随意发布有关我的postfix conf文件的其他build议/问题..
