by Rene Plattner 04 May '08

04 May '08

Dear stunnel users! I noticed that the xforwardfor patch does not work any more on version > 4.20! This is due an function renaming in stunnel! After adding xforwardfor patch for version 4.20 see options.c: Simply replace log_raw(...); to s_log(LOG_RAW,...); chears, -- Dipl.-Ing.

Can stunnel be configured to listen for multiple IP addresses and access different email hosts?
by F Boyd Crow 03 May '08

03 May '08

I have attempted to use stunnel to retrieve POP3 SSL mail from two different ISPs: pop.att.yahoo.com and pop.gmail.com. I have tried putting in separate Access/Connect line pairs under [pop3s] either point to the different ports on 127.0.0.1 whch is an Exchange Server 2003 machine. I have tried pointing both to the same port. In either case, the first POP3 host is accessed but not the second. I have also tried one Access line and two separate connects. It works fine with one Access line and one Connect line but a previous post on this subject indicated I should be able to do retrievals from two separate sites and I do not see how. I am using the POP3 Connection Manager on Small Business Server 2003. I set the email server to 127.0.0.1 and use port 9995. The corresponding section of the stunnel.conf file is client = yes debug = 7 ; Service-level configuration [pop3s] accept = 9995 connect = pop.gmail.com:995 ;does not work with two separate pop3s, either with two separate accept ports or one common final comment is my own. Has anyone successfully accessed mail from two POP3 servers through stunnel or have any suggestions? Boyd

Re: [stunnel-users] launch stunnel server daemon from php?
by Wesley Kenzie 02 May '08

No, that does not work either. I can get stunnel to start fine outside of php, but not as an exec or shell_exec from within a running script, or even from within php -a interactively. I can get other programs to work fine this way, so it is specific to the stunnel executable as best I can tell. I have tried running various forms of bash scripts too, but none do any better. Ideas? . . . . . Wesley On Fri, May 2, 2008 at 12:52 PM, Ludolf Holzheid < lholzheid(a)bihl-wiedemann.de> wrote: > On Fri, 2008-05-02 12:32:19 -0700, Wesley Kenzie wrote: > > Yes.

Yes. Without this stunnel would not launch. With foreground = no and with the trailing & on the command line I got it to launch, but still control will not return to my php script ... . . . . .
