Hi Timo, Are there any plans to support the SIZE option in the lmtp server?

So that RCPT commands would fail if the size would bring user over quota? I guess I could implement it someday soon.

Actually, it looks like it would be difficult to implement without dirty hacks. Maybe later.

I guess SIZE optimizes the process. You can reject *before* DATA, at RCPT TO stage.

yes of course it would ,but tried to write a postfix policy server which does like this but its extrem ugly, i stopped it ,and know now why its not allready done by others, the main probelem is that you never know the real size of a mail until its fully got ( or late got , and there many other problems too i.e can i trust the client about size he gave etc), but with dove2 lmtp and postfix asks dove2 lmtp in smtp income stage about quota so mail can be bounced overquota before the con is finished what means the main problem i.e thinkable backscatter cause by overquota is fixed that way. ( behave that i tested, hopefully right) alternate you can use postfix with the vda patch ( not remommended by orginal developers of postfix ) , dont looked in their patch how solved the quota problem, but if you use it ,you will loose filtering with sieve done by lda or lmtp , cause it delivers directly to maildir, other soltuion ( smtp proxy milter etc ) may always ask th quota by backplained real mailservers smtp process, so for now to me it looks like dove2 with lmtp ist the best solution you can get at the moment , or write yourself a policy daemon etc finally the theme is that complex that i might fail here with tec details, but this is my current knowledge, perhaps some others have better ideas/knowledge recently
