Sending mail takes ages.

["Pete Clarke" <pete@devilincarnate.eclipse.co.uk>]

Hi all,

I have a Debian sarge mailserver, running exim4-daemon-heavy, 
courier-pop/imap etc.

When collecting email or using IMAP everything runs very well indeed, 
however, when sending mail from a standard client (OE, Squirrelmail, Kmail, 
Evolution, OSX mail app etc.) there is a long delay, upto a minute, before 
the authentication process kicks in and the mail is sent.

I am authenticating against an LDAP server (which is running on the same 
box), all other authentications (PAM,  Samba etc.) are instantaneous, it's 
just sending mail that takes forever.

I have googled, but to to avail.. any ideas?

Cheers,


Pete.
