Hi Eric, I have one doubt regard the create certificate.
I have gone through this link https://www.qmailtoaster.org/ssl.html It was showing the six steps. Do i need to complete all the six steps or just use only the below second steps only for my server COS 6 & 7 32 and 64 bit. Please help me. 1. Application: Self-Signed Certificate 1. # openssl genrsa -out x.key 2048 2. # openssl req -new -key x.key -out x.csr 3. # openssl x509 -req -days 3650 -in x.csr -signkey x.key -out x.crt 4. # cat x.crt x.key > servercert.pem 5. # chmod 644 servercert.pem 6. # chown root:qmail servercert.pem 7. # cp -p servercert.pem /var/qmail/control On Tue, Aug 14, 2018 at 11:03 AM, ChandranManikandan <[email protected]> wrote: > Hi Eric, > > Thank you, Let me try it and update here. > > On Tue, Aug 14, 2018 at 10:54 AM, Eric Broch <[email protected]> > wrote: > >> I've installed certificates on both CentOS 6 & 7 using GoDaddy and >> LetsEncrypt. >> >> On 8/12/2018 9:12 PM, ChandranManikandan wrote: >> >> Hi Eric, >> >> I think i already installed the certificate which was 512 and got expired >> on the server. >> >> Can i try to install the certificate which you advised and sent link >> earlier. >> >> I just want to make sure, the problem will not come after install this in >> the production server. >> Have you tried in COS6 32 and 64 bit server. >> Because am running both the version in different server. >> >> >> >> On Fri, Aug 10, 2018 at 2:03 PM, Eric Broch <[email protected]> >> wrote: >> >>> Office 365 my require a signed certificate from a Certificate Authority. >>> >>> On 8/9/2018 10:23 PM, ChandranManikandan wrote: >>> >>> Hi Eric, >>> >>> I think the certificate was expired and the date is in server -rw-r--r-- >>> 1 root qmail 1.7K Mar 22 2013 servercert.pem >>> >>> I have checked the certificate validity in outlook while opening. >>> >>> FYR.
