Time out error

[drdre]

hi all,

I have my SQL application sending emails through our zimbra server to our clients (their monthly invoices).

Now it works, but for some of our customers we send multiple emails to the same address .. The error i am getting is "Lost Connection with mail.whatever.com while sending mail."

Some clients we are sending 20+ emails with their invoices to the different departments but same email server .

Is there a way to increase the timeout period ? or connection time ?

Regards,
Andre
