Log4net SmtpAppender configuration to receive chunks of log - winforms

Question

I would like to save everything in a log file and receive mails containing 512 messages per mail.
RollingFileAppender works fine. But in emails I receive sometimes 1 message in mail, sometimes 4 messages (not the same ones).
I tried MemoryAppender too. There I have also 1-2 messages in queue, nothing more.
I tried "lossy" SmtpAppender, the result is same. What should I change?
My configuration is here
<log4net>
<appender name="RollingLogFileAppender" type="log4net.Appender.RollingFileAppender">
<file value="c:\temp\log-" />
<bufferSize value="0" />
<appendToFile value="true" />
<rollingStyle value="Composite" />
<param name="DatePattern" value="yyyy.MM.dd'.log'" />
<maxSizeRollBackups value="-1" />
<maximumFileSize value="10MB" />
<staticLogFileName value="false" />
<layout type="log4net.Layout.PatternLayout">
<conversionPattern value="%date %-5level - %message%newline" />
</layout>
</appender>
<appender name="SmtpAppender" type="log4net.Appender.SmtpAppender">
<bufferSize value="512" />
<lossy value="false" />
<authentication value="Basic" />
<to value="test#test.com" />
<from value="test#test.com" />
<username value="test#test.com" />
<password value="xxxxx" />
<subject value="My subject" />
<smtpHost value="mail.test.com" />
<layout type="log4net.Layout.PatternLayout">
<conversionPattern value="%date %-5level - %message%newline" />
</layout>
</appender>
<root>
<level value="ALL" />
<appender-ref ref="RollingLogFileAppender" />
<appender-ref ref="SmtpAppender" />
</root>
</log4net>

The following appender config works for me (I get 6 log messages at a time):
<appender name="SmtpAppender" type="log4net.Appender.SmtpAppender">
<to value="name#server.com" />
<from value="name#server.com" />
<subject value="Log Email" />
<smtpHost value="email.test.com" />
<bufferSize value="5" />
<lossy value="false" />
<layout type="log4net.Layout.PatternLayout">
<conversionPattern value="%property{log4net:HostName} :: %date %level %logger [%thread] - %message%newline" />
</layout>
</appender>
Do your log messages have multiple lines perhaps?
