Before was all ok, but now when i try to send a msg i receive this error "unable to set sender to [my@mail]." I dont know how i can find ant fix the error because this is the unique messages that i have. Maybe it's possible the configuration of the antispam and the change of the listenings ports or what? I have problems only on webmail, if i use my mails with a client (ex. outlook) works without problems. I use plesk 9.0 (updated from 8.6 but before i had the same error) with windows 2003 SE server. Sorry for my english and thanks in advance for any help you can give me. Daniele.

Probably something changed in your MTA configuration.

Probably something changed in your MTA configuration. Hello, But sound strange 'cause only on the webmail i cant send to anybody but i receive without problem. I'made a mailenable test and all the test passed. The difference from before and now it's only the antispam's installation and the insert of a blacklist zone but i think isnt this the problem because ifi use my mail on a external client all working perfect. Please tell me if u need some logs or what because i dont know what i can do for resolve this situation :( Regards, Daniele Fri, 30 Jan 2009 09:00:30 +0000 https://bugs.horde.org/ticket/7897#t52137 This is not a support forum.
