Sujet: [exim] Strange problem with MySql lookup
Hi all,

i have a strange problem with an MySQL lookup;
many, many lookups work without any problem then I get errormessages like

2006-10-03 17:02:39 H=horn02.intern.ebewe.at (horn.intern.ebewe.at)
[172.16.5.102] sender verify defer for <removed_by_me!>: condition check
lookup defer
2006-10-03 17:02:39 H=horn02.intern.ebewe.at (horn.intern.ebewe.at)
[172.16.5.102] F=<removed_by_me!> temporarily rejected RCPT
<angiola.aloisio@???>: MYSQL connection failed: Unknown MySQL Server
Host 'saxophon' (1)

after exim restart everything is fine

Here is my exim version:
