The selfsigned certificate will expire today (05 Jan 2010) @ about 0700H GMT. Having known the expiry date, I renew the selfsigned certificate yesterday. Renewal using the admin GUI is successful as reflected on the new validation date. I thought everything is going fine.
However, just recently at about same time as the previous expiry (o5 Jan 2010) the mail server stops sending and receiving mails. I look at the logs and I noticed continous messages like " mail kernel: IPT TCPDUMP: IN=eth0 OUT= MAC=00:1b:b9:86:bf:2f:00:1e:58:31:bc:70:08:00 SRC=18.104.22.168 DST=xxx.xxx.xxx.xxx LEN=48 TOS=0x00 PREC=0x00 TTL=109 ID=24963 DF PROTO=TCP SPT=13411 DPT=17088 WINDOW=65535 RES=0x00 SYN URGP=0
i suspect that this is because of the certificate.
Could somebody form zimbra help me restore on this.
