Hi!

I have noticed that the smtp doesn't allow to send mails from foreign addreses (field "sender" with an e-mail from a different host). And also I can't send mails with big attachments. Can I somehow set up this features?

Thanks 

Sending email from a foreign address is known as forging headers, which puts your email (and SMTP server) at high risk of being flagged as a SPAM or Open-Relay server.  This is a big no-no.  SMTP Authentication helps prove that you are sending the email through an SMTP server that can authenticate you, which results in less SPAM being sent.

As far as sending large attachments, how large?  SMTP servers can control how large of an attachment it will allow.  This is to keep things flowing so the server/network is not bogged down.  If you are trying to email large files, consider FTP instead of email.

Thanks.

Attachment was about 10Mb, but it's Okay. My questions was if I can setup this settings myself.

10MB probably exceeds the limit Ultima has set.

Within SmarterMail you can set your own limitation on file size, but I believe if your limit is higher than Ultima's that Ultima's will override your setting.  Ultima would need to confirm/clarify though.
