Hello,
At home I have my WLAN as 192.168.2.0/24. After moving to my office and
rebooting there, I encounter that sendmail receives messages (via
fetchmail) terrible slow. I digged into this and see that the sendmail
issues wrong DNS requests as (for example):
08:51:18.753491 IP xx.xx.xx.xx.49812 > 192.168.2.1.53: 12793+ MX?
ubuntu.com.Sisis.de. (37)
08:51:18.867365 IP xx.xx.xx.xx.42619 > 192.168.2.1.53: 12793+ MX?
physik.uni-wuerzburg.de.Sisis.de. (50)
08:51:18.982491 IP xx.xx.xx.xx.52554 > 192.168.2.1.53: 12794+ AAAA?

08:51:19.095490 IP xx.xx.xx.xx.10093 > 192.168.2.1.53: 12794+ AAAA? des.no.
(24)
The reason is obvious:
- the /etc/resolv.conf on shutdown at home has this DNS resolver;
- in my office the system comes up and when at some point the WLAN
interface associates, it gets an IP and a new /etc/resolv.conf file;
Why sendmail does not honour the new /etc/resolv.conf and stays with the
old DNS server IP? How this is supposed to fix? An idea would be to
restart sendmail via a devd hook, but maybe there is some config values
for sendmail that it always check /etc/resolv.conf for fresh?
Thx
matthias
