Re: [Dovecot] pop3 proxying error

Hi Timo, I've got some errors with pop3 proxying and dovecot 2.1.9

I's occured on the proxy side:

Aug 7 13:16:47 dev1 dovecot: pop3-login: Fatal: master: service(pop3-login): child 23046 killed with signal 11 (core dumped)

Server side shows no error, and runs the same dovecot version.

Thanks for your help. Best regards Tonio Buonaguidi
