[Dovecot] file descriptor errors

[Christian Rößner]

Hi,

just a short question: I had sent exactly this same email with a wrong email address (not the cr at sys4.de) and unfortunately I was to late deleting it in Mailman. Now I get replies to the c at roessner-network-solutions.com address, which will not succeed at the moment, because of DMARC policy. So if you already sent answers, could you please email it again to the cr at sys4.de mail. Thanks a lot in advance
