The default value for the SMTP server port value has been changed to 25. Mail sent to multiple recipients may repeat and send the message to the recipients more than once. When mail is addressed to more than one recipient many email servers will store one copy for each recipient. IGetMail recognizes the duplicate messages and only sends the mail to each user once. IGetMail checks for the duplicate message as it is downloading the message.
Some email servers can handle concurrent communications and other servers become confused.
If the email server becomes confused, it would ignore IGetMail's attempts to delete the duplicate message, causing the email server to regenerate the message. Multi Mega byte messages seem to download slowly over very high speed data lines. The SMTP Server receives email but cannot determine who sent it. In both cases, the email server did not who to address the reply or bounce back to. Note this is only active on group accounts.
