Ok, thank you for your help :)

Looks like we talked at cross-purposes. The Horde Vacation module has 
nothing to deal with the sender of the original messages at all. This 
is all handled by the local system vacation executable. Horde Vacation 
is only responsible for creating the actual vacation message, not for 
sending it. It does encode the original recipient's (the sender of the 
vacation notice) name just fine.

I've now tried and tested horde on a fresh install of RHEL5 on a test 
server. Still I have the same problem. I've included with this comment 
a file that contains all my data gathered regarding this problem.



Thank you,

It works perfectly for me with this name.

Yes I know, but this is not: <=?utf-8?b?VMOkc3RhcmUg?=@servername.domain.tld>



If the user has the name Kålle Kår then the to field will look like 
the above, and sendmail will not recognize the email address. If I as 
the sender of the email on the other hand remove the scandinavian 
characters from my name in the default identity in horde, reply 
vacation messages will be sent out to the sender from the recipient 
who has vacation activated.



It is such a weird problem. I am totally baffled, and I do not know if 
this is a bug in sendmail, the vacation binary, horde, imp or the 
vacation horde module. I'm setting up a test enviroment on a server 
now where Horde, Imp, Ingo, Turba and Vacation are HEAD cvs releases 
(2007-05-03), to see if the same problem exists with the dev releases.

What's wrong with that? It's a perfectly valid From: header.

Well, I found another weird problem.



If a sender has for example the name : Kalle Kållbacka then a vacation 
message is sent out, but if a sender has the name Kålle Kållbacka then 
no message is sent out.



Another side effect, is that if the recipient has Vicki Swärd, then on 
the vacation reply will be sent out, but the name in the folder view 
in imp will look like VickiSwärd. The following is an email message 
source demonstrating this effect:

I'm on vacation and will not be reading my mail for a while.

Your mail will be dealt with when I return.

Is this a Horde, Imp or Vacation bug?





Thx,

/PGE

See bug report : http://bugs.horde.org/ticket/?id=5303



I've found some weird bugs with the latest HEAD (3.1-cvs) version of vacation.



If a sender of a mail has a name that contains one or more 
scandinavian characters like åäö,ÅÄÖ in the name, a vacation mail is 
not sent. If the same user removes all scandinavian characters, then a 
vacation reply is sent out. See extracts from maillog.
