Sometimes problemens sending
Hi,
after creating backup sometimes the mail is sent successfully, but sometimes (I didn't touched anything) emails were not send. The log shows me:
250 smtp.strato.de greets 2.247.*.*
250-smtp.strato.de greets 2.247.*.*

The next day it looks like this:

The backup-job is exactly the same in these cases.
Ideas?
Thanks in advance

Re: Sometimes problemens sending
For some reason (page code, inner SMTP server config) the SMTP server is trying to interpret the HTML in the e-mail, which goes inside the DATA command, as if it was part of the protocol conversation. Easiest way to solve it is to use some other SMTP server.
