Hi. I have 2 email domains for my server. Server has 2 ips, one is external, to reach from internet. Another ip is internal, to make data exchange inside local network. One domain email work properly, i can reach webmail and receive letsencrypt ssl. But another email address suddenly has internal ip in configs. When i try to change it manually to external ip, i can reach webmail. But when I try to get SSL for email domain, all settings reset back, I have again internal IP for email domain and of course I cant get ssl certificate for it.
Long time ago I set test[dot]domain[dot]com as web and domain.com as email domain. domain[dot]com as web was on another server. But when I set for test[dot]domain[dot]com alias domain.com and www[dot]domain[dot]com, settings for email domain[dot]com changed to internal IP suddenly (why???). I solve problem by removing domain[dot]com as alias and set it as real web domain. Thanks.
