Stephen, Can you please provide a bit more detail and your setup. To me the issue maybe DNS record related, but I am not sure. I am guessing mail.stackmail.com certificate has expired or is self-signed? But I am not sure how to check this.
Do you use any DNS caching on your computer? Can you try a different computer? Is insilicochemistry.net your web site, and do you also have one or more MX records (insilicochemistry.net, and mail.insilicochemistry.net) in your web site's DNS that point to mail.stackmail.com ? Below is some DNS name checking that I did, the results confuse me. I am guessing that your web site insilicochemistry.net is hosted on scluster24.stablehost.com and your email server is hosted on mail.stackmail.com? If so, what happens if in your Epyrus email client, you use mail.stackmail.com and not mail.insilicochemistry.net ? Epyrus is not packaged with Debian, hence I expect that you downloaded it and installed it? http://www.epyrus.org/ https://mxtoolbox.com/SuperTool.aspx?action=mx%3ainsilicochemistry.net&run=toolpage Pref Hostname IP Address 10 mx.stackmail.com 185.151.28.67 $ dig mx mail.insilicochemistry.net +short mail.stackmail.com. gkirkham@debkde05:~$ dig mx insilicochemistry.net +short $ dig -x 213.109.149.117 +short scluster24.stablehost.com. $ nslookup insilicochemistry.net Non-authoritative answer: Name: insilicochemistry.net Address: 213.109.149.117 $ nslookup insilicochemistry.net -type=mx Non-authoritative answer: Name: insilicochemistry.net Address: 213.109.149.117 $ nslookup 213.109.149.117 117.149.109.213.in-addr.arpa name = scluster24.stablehost.com. $ nslookup 213.109.149.117 -type=mx Non-authoritative answer: 117.149.109.213.in-addr.arpa name = scluster24.stablehost.com. $ nslookup mail.insilicochemistry.net Non-authoritative answer: mail.insilicochemistry.net canonical name = mail.stackmail.com.
