I've setup a new domain on server. the outgoing mails are working fine but there is an issue with incoiming mails - none has been received so far.
DNS settings:

online-business.pl. MX 10 mail

How to investigate the issue?
 
- Is online-business.pl listed in /etc/virtual/domains?

- Are you able to check the mail logs from another mailserver? In that case you can send an email to an @online-business.pl address and check whether the email has been delivered or if there's some error.
 
1) yes, it's listed in /etc/virtual/domains


2) ----- The following addresses had fatal errors -----
[Status: Error, Address: <[email protected]>, ResponseCode 421, Host not reachable.]

Message will be retried for 4 more day(s)
 
what I see now in /var/log/exim/mainlog is

X=TLSv1.2:DHE-RSA-AES256-SHA256:256 CV=no F=<xxx@xxx> rejected RCPT <[email protected]>: Sender verify failed

any help in resolving it is highly appreciated
 
Hello,

exim.conf has this section:


Code:
addresslist whitelist_senders = nwildlsearch;/etc/virtual/whitelist_senders
domainlist whitelist_domains = nwildlsearch;/etc/virtual/whitelist_domains
hostlist whitelist_hosts = nwildlsearch;/etc/virtual/whitelist_hosts
hostlist whitelist_hosts_ip = /etc/virtual/whitelist_hosts_ip


so use the files:

/etc/virtual/whitelist_senders
/etc/virtual/whitelist_domains
/etc/virtual/whitelist_hosts
/etc/virtual/whitelist_hosts_ip

to whitelist trusted senders for which a sender verification fails.

I'd rather try and investigate why sender verification failed.

p.s. search the forums and help.directadmin.com for details on how to use the files.
