How to configure IMAP and SMTP servers

[Aido21]

Yap, It should be better

IMAP & SMTP - clients connected but no communications with other servers

Operating system: Ubuntu OS version: 20.04 Hi, it is the second issue on my way to the happiness with Virtualmin :-). For outgoing mail it looks like the messages are received by postfix - I can see them in the Mail Queue but the postfix cannot connect to the recipient’s server - I see the connection timeout messages What about Dovecot - I have no idea where to look - the remote sender “successfully” send the mail without any errors but I cannot see it in my inbox.
