Ahoj obcas se mi stava ze se objevuje tato hlaska. Pravidlo je v poradku. Nekdy se to stane 3x za den a jindy se to stane az treba za mesic ale stava se to. Co s tim? Do slozky se i tak vetsinou presune a kdyz ne a pravidla spustim manualne tak se presune.
Pouzim IMAP od Seznam.cz
Sender: [name hidden]@seznam.cz: An error occurred
Recipient: [IMAP] The message failed to upload repeatedly, which may be caused by server incompatibility.
Could be your SMTP mail settings are not right, or could be an older version of eM Client that might possibly need updating, or could be a something interfering with the upload running resident, or could be an actual mail server issue.
So first thing update what your account SMTP mail “Server address, Server Port and Security Policy” is so we can see if there is any obvious errors.
Also update “what version of eM Client you are using” and if you have Windows or Mac and OS ver.
Also are you trying to send large attachments and get the uploading error when doing that? Or does this error happen with even plain text messages.
Also are you running and optionally installed Firewall / Security programs or optionally installed Antivirus programs or vpns other than the default OS stuff.
