Remember that avast handles more than one SMTP server, to configure your e-mail client (program) follow these steps:
1. Close all your email applications.
2. Start Windows Menu > avast! antivirus > Mail Protection Wizard
3. Click Next on the first screen
4. Choose 'Setup the protection manually'
5. Choose 'I don't use MS Outlook (nor MS Exchange client) or
'I use other programs to work with e-mails as well'
a) with MS Outlook/Exchange, the Wizard finishes here.
b) with another e-mail client:
After the service was disabled, choose Next
Select your e-mail accounts (or 'My accounts is not in the list...' to get help)
Finish your configuration and the service will start again.
You can run the Mail Protection Wizard more than once and all the changes could be reversed ('Automatically remove protection from all my accounts'). Nowadays, the following Internet Mail Clients are supported: MS Outlook (including Outlook 2003), MS Exchange, MS Outlook Express, Eudora, Pegasus Mail, Netscape Mail, Mozilla Mail, IncrediMail and The Bat!
If this not help, you, try the help file Manual setting of mail protection. Launch your mail program and let the program display the account settings.
1. If you want to check outgoing messages, change the address of SMTP server to the address of the local computer, i.e. 127.0.0.1. The localhost or 127.0.0.1 is the way to scan your outbound mail.
2. If you want to check incoming messages, change the address of POP (IMAP) server to the address of the local computer, i.e. 127.0.0.1. The localhost or 127.0.0.1 is the way to scan your inbound mail.
3. Change user (login) name this way: append the character # (double hash) and the address of your POP (IMAP) server (the same as you specified in the avast4.ini file in Step one). Login name should then look like this:
yourname#pop3.server.com
4. If your e-mail program supports SMTP authentication and also makes it possible to set a different login name for SMTP than for POP
5. If the SMTP authentication is enabled, append the character # and the address of your SMTP server to the login name (e.g. yourname#smtp.server.com).
6. If the SMTP authentication is disabled, enable it and use the character # together with the address of your SMTP server as the login name (e.g. #smtp.server.com).
7. Save your changes.
