The correct way has to be one or the other: http://wiki.dovecot.org/LDA/Exim are mutually exclusive with http://wiki.dovecot.org/HowTo/DebianStable It appears that exim can either call dovecot's LDA or make the delivery itself.

After much googling, it appears that one can use either exim or dovecot as the LDA - the trade offs are not clear. It seems that the amount of mass mails all needing to get indexed at the same time would make dovecot as the LDA create a higher server peak, -- I think the inbox is only indexed in the case of exim as the LDA when users check their mail - thus spreading the load. On the other hand, I don't see where the advantage of using dovecot as the LDA is documented. It could be important for indexing, caching. ---------------------------------------------------------------- Karl Schmidt EMail Karl at xtronics.com Transtronics, Inc.

At the moment, I use Exim and Dovecot, and have things set up to use imapd, using Dovecot as the LDA. It worked fine for a while, but with upgrades I am now unable to send email out using Thunderbird (for example - this applies to KMail and Sylpheed as well). Exim treats it as a relay, and bans it. Curiously, using these from another machine works fine. Also fine is sending mail internally, from a cron job for example, or to external addresses from my website. It seems that the router setting in Exim is the problem, and the better solution is to use Exim as the LDA, but if one does not use Dovecot as the LDA, what's the point of having it? I installed it originally to be able to use Squirrelmail when I'm on the road. Now I'm using it all the time. What am I missing here?
