Symptoms
- WorkgroupMail is configured to ‘Send mail directly’ but the messages are not being sent.
- The diagnostics in WorkgroupMail v7 and v8 indicate a DNS error on port 53.
Resolution
If you are certain that WorkgroupMail has internet access then the problem is most likely to be with the DNS server addresses.
WorkgroupMail v8 and v7
Double click the Domain configured in WorkgroupMail and select the Sending tab. ‘Direct’ should be selected. Double click the Smart Host Settings and check that this contains the addresses of two internet DNS servers.
To test that your DNS servers will resolve domain names, click Edit, Run Diagnostics. Failure to resolve addresses using DNS will be reported as an error on port 53.
WorkgroupMail v6
Double click the ISP configured in WorkgroupMail and select the Servers tab. ‘Send mail directly’ should be selected and two internet DNS server addresses entered into the boxes.
To test that your DNS servers will resolve domain names, use NSLookup at a command prompt.
eg. C:>nslookup -qt=mx domain.com. 158.152.1.58
NB 158.152.1.58 is the DNS server address
NB The trailing period character after the domain name is important
Server: cache-1.ns.demon.net
Address: 158.152.1.58
Non-authoritative answer:
domain.com MX preference = 50, mail exchanger = server3.domain.com
domain.com MX preference = 10, mail exchanger = server1.domain.com
domain.com MX preference = 30, mail exchanger = server2.domain.com
domain.com MX preference = 50, mail exchanger = server4.domain.com
etc.
