First of all, I'm using evolution as the client. I have no idea what you mean by mechs, but I guess I'm using whatever the Fedora Core default is, unless that is altered in /etc/mail, and I have no idea what 'saslauthd' is. I checked the dates on the files in /etc/mail against the dates in my backed up /etc/mail from the server PC and found that I had not extracted them over correctly. I have now fixed that. Now when I try to send mail from outside my domain to inside it, I get the mail returned from my domain's postmaster saying ----- The following addresses had permanent fatal errors ----- <michael@xxxxxxxxxxxxxxxx> (reason: 553 5.3.5 system config error) ----- Transcript of session follows ----- 553 5.3.5 espersunited.com. config error: mail loops back to me (MX problem?) 554 5.3.5 Local configuration error Please don't flame me. I'm under a lot of stress. This network is all I have and it's not working right at the moment. I'll try to delete all traces of replying to other threads in the future, but I can't use evolution's address book because the address-book backend crashes every time I try to use it (a topic to be saved for a different thread) and I can't be expected to remember email addresses for the twenty or so mailing lists I'm subscribed to... -Michael Sullivan- On Sat, 2004-06-12 at 11:44, Alexander Dalloz wrote: > Am Sa, den 12.06.2004 schrieb Michael Sullivan um 18:27: > > First: Please do not hijack foreign threads!
