Which client? which operating system? More info is appreciated These log lines indicate a imap login, while a SMTP log line would be written by Postfix and not Dovecot. Seems like it's simple: there is no A record for mail.wp-fit.com. By the way, I would recommend not giving each domain their own mail. subdomain Writing a post on it now, will send you the link later
Hi there, thanks a lot for your answer and the post how to setup email. Now its more clear to me however i would like to ask some more questions if it does not bother. 1. if i have many domains on a server, do i need to setup smtp.domain.com and imap.domain.com for each domain or is there another solution for that? 2. should i setup one mailserver on an extra server (not the same like the webserver) like smtp.mydomain.com and imap.mydomain.com for all the domains i have on several servers? So if i have 1 domain on a server like newweb.com i can setup newweb.com with smtp.mydomain.com and imap.mydomain.com ? i am a bit confused about that. OR should i use the servername like imap.server1.com and smtp.server1.com? 3. to fix my problem should i delete mx record mail.mydomain.com and setup smtp.mydomain.com and imap.mydomain.com ? or would it be better to add an A Record for mail.mydomain.com? As i have more servers i would like to use the correct way for the future as well. 4. my email client is evolution on linux ubuntu 21.10 system. 5. the mailserver settings on my evolution is as follows: I use actually : imap : server: server1.myserver.com port 993 TLS on dedicated port smtp: server: server1.myswer.com port 587 Tls on dedicated port is this correct ? and what would be pop 3 for the same email? Thanks a lot for your kind help on a sunday
Read the post again It clearly tells you example.com is your own domain and you should not add additional names for every client. You can let every user use smtp.example.com and imap.example.com and host their email domain on the separate mailserver. For a quickfix, set up a A record. For a good fix, set the mx record to point to mx1.example.com or whatever the hostname of the mailserver is Like I explained in the other post, use smtp.example.com and imap.example.com and set up a cert for that.
Hi, thanks for your detailed answer. I understand that for a good solution to setup my own mailserver on a separate server with mx1.mycompanyname.com and mx2.mycompanyname.com So every domain on the server client-domain.com use these mx1 and mx2 domains as mailserver. How do i setup a mailserver is there a post how to do that with ubuntu and ispconfig? would it be ok to setup an ispconfig standard install (automatic installation) according to: https://www.howtoforge.com/ispconfig-autoinstall-debian-ubuntu/ thanks a lot for you help and sorry for not understanding that yet

Hi thanks for your answer. what email do i need to send a message for get the paid support. I would like to check out what is going on on the servers why it does not work to send emails, i have checked my other servers and have the same problem that i can not send emails so there must be a fault. To make the A record did not solve the problem.
