[9fans] upas/fs -f/imap & Courier

[Matt H]

Well I eventually got it to log in OK

this bit relies on the text output of the OK message from the IMAP server which is imlpementation dependent and not part of the spec (see the OK line below for what Courier outputs)

272c276,277
< 	if(!isokay(s) || strstr(s, "IMAP4")==0)
> 	if(!isokay(s) || strstr(s, "IMAP")==0)

However even when I got it to log in it failed reading (debug output below)

it ran out of lines to read and ended returning Eio ("i/o error") in this routine

static char*
imap4resp(Imap *imap)
{
	char *line, *p, *ep, *q, *r, *verb;
	int n;

	while(p = Brdline(&imap->b, '\n')){
		.. snip
	}

	return Eio;
}

Re: [9fans] upas/fs -f/imap & Courier - SOLVED

Courier has a setting for maximum connections per IP, I had it set to the default(4)
I bumped it up and now it's working just fine

in file : /usr/local/etc/courier-imap/imapd
MAXPERIP=40

here's the diffs again because I noticed my comments were bumping the line numbers :
/sys/src/cmd/upas/fs/imap4.c

This test (in either form) is just plain wrong and should be
removed. There is no requirement for the string IMAP to
appear anywhere in the greeting:

greeting        ::= "*" SPACE (resp_cond_auth / resp_cond_bye) CRLF

resp_cond_auth  ::= ("OK" / "PREAUTH") SPACE resp_text
                    ;; Authentication condition

resp_cond_bye   ::= "BYE" SPACE resp_text

resp_text       ::= ["[" resp_text_code "]" SPACE] (text_mime2 / text)
                    ;; text SHOULD NOT begin with "[" or "="
